In physics, sputtering is a phenomenon in which microscopic particles of a solid material are ejected from its surface, after the material is itself bombarded by energetic particles of a plasma or gas. It occurs in outer space, can be an unwelcome source of wear in precision components. However, the fact that it can be made to act on fine layers of material is utilised in science and industry—there, it is used to perform precise etching, carry out analytical techniques, deposit thin film layers in the manufacture of optical coatings, semiconductor devices and nanotechnology products; when energetic ions collide with atoms of a target material, an exchange of momentum takes place between them. These ions, known as "incident ions", set off collision cascades in the target; such cascades can take many paths. If a collision cascade reaches the surface of the target, its remaining energy is greater than the target's surface binding energy, an atom will be ejected; this process is known as "sputtering".

If the target is thin, the collision cascade can reach through to its back side. The average number of atoms ejected from the target per incident ion is called the "sputter yield"; the sputter yield depends on several things: the angle at which ions collide with the surface of the material, how much energy they strike it with, their masses, the masses of the target atoms, the target's surface binding energy. If the target possesses a crystal structure, the orientation of its axes with respect to the surface is an important factor; the ions that cause sputtering come from a variety of sources -- they can come from plasma, specially constructed ion sources, particle accelerators, outer space, or radioactive materials. A model for describing sputtering in the cascade regime for amorphous flat targets is Thompson's analytical model. An algorithm that simulates sputtering based on a quantum mechanical treatment including electrons stripping at high energy is implemented in the program TRIM. Another mechanism of physical sputtering is called "heat spike sputtering".

This can occur when the solid is dense enough, the incoming ion heavy enough, that collisions occur close to each other. In this case, the binary collision approximation is no longer valid, the collisional process should be understood as a many-body process; the dense collisions induce a heat spike, which melts a small portion of the crystal. If that portion is close enough to its surface, large numbers of atoms may be ejected, due to liquid flowing to the surface and/or microexplosions. Heat spike sputtering is most important for heavy ions with energies in the keV–MeV range bombarding dense but soft metals with a low melting point; the heat spike sputtering increases nonlinearly with energy, can for small cluster ions lead to dramatic sputtering yields per cluster of the order of 10,000. For animations of such a process see "Re: Displacement Cascade 1" in the external links section. Physical sputtering has a well-defined minimum energy threshold, equal to or larger than the ion energy at which the maximum energy transfer from the ion to a target atom equals the binding energy of a surface atom.

That is to say, it can only happen when an ion is capable of transferring more energy into the target than is required for an atom to break free from its surface. This threshold is somewhere in the range of ten to a hundred eV. Preferential sputtering can occur at the start when a multicomponent solid target is bombarded and there is no solid state diffusion. If the energy transfer is more efficient to one of the target components, or it is less bound to the solid, it will sputter more efficiently than the other. If in an AB alloy the component A is sputtered preferentially, the surface of the solid will, during prolonged bombardment, become enriched in the B component, thereby increasing the probability that B is sputtered such that the composition of the sputtered material will return to AB; the term electronic sputtering can mean either sputtering induced by energetic electrons, or sputtering due to high-energy or charged heavy ions that lose energy to the solid by electronic stopping power, where the electronic excitations cause sputtering.

Electronic sputtering produces high sputtering yields from insulators, as the electronic excitations that cause sputtering are not quenched, as they would be in a conductor. One example of this is Jupiter's ice-covered moon Europa, where a MeV sulfur ion from Jupiter's magnetosphere can eject up to 10,000 H2O molecules. In the case of multiple charged projectile ions a particular form of electronic sputtering can take place, termed potential sputtering. In these cases the potential energy stored in multiply charged ions is liberated when the ions recombine during impact on a solid surface; this sputtering process is characterized by a strong dependence of the observed sputtering yields on the charge state of the impinging ion and can take place at ion impact energies well below the physical sputtering threshold. Potential sputtering has only been observed for certain target species and requires a minimum potential energy. Removing atoms by sputtering with an inert gas is called ion ion etching.

Sputtering can play a role in reactive-ion etching, a plasma process carried out with che

Hallsville, Texas

Hallsville is a city in Harrison County, United States, located 13 miles west of the county seat, Marshall, on U. S. Highway 80; the population was 3,577 at the 2010 census, up from 2,772 at the 2000 census. The area was first settled in 1839, when Fort Crawford was built one mile west of the site of present Hallsville by W. C. Crawford as a protection against Indians. In 1849 the fort is reported to have had a post office and a two-story building that served as church, Masonic hall, school. In 1869, when an independent Southern Pacific Railway crossed a mile north of Fort Crawford, the settlers moved to the railroad and named the new settlement for a railroad official. All that remains at the original location is a cemetery. A post office named "Hallville" opened in 1869, the first business in the new community was a saloon. From 1869 to 1872 the town was the terminus of the railroad, the railroad company built a general office and machine shops there; the community incorporated for the first time in 1870 and was a boom town, with as many as fifty businesses, in the early 1870s.

Hallville shipped cotton and hides. In 1872, when the Texas and Pacific acquired the railroad and built out to Longview in Gregg County, Hallville lost much of its western trade. In 1873 the railroad moved its local shops to Marshall. Hallville's incorporation lapsed, the community lost many of its people to Marshall in the 1870s. In 1884 it had an estimated 600 inhabitants, three churches, six sawmills, six grist mill-gins, a hotel, two saloons, a cooperative association. By 1892 the population had fallen to 300. In 1904 the Hallville school district had two schools serving 180 white pupils and one school serving 111 black pupils. A bank opened in the community in 1909. In the 1920s the post office changed the spelling of its name to Hallsville; the community reincorporated in 1935. Until 2003, Hallsville had only one traffic light, located at the main intersection at Main Street and FM 450; the town has experienced rapid growth in the past decade and now boasts five traffic lights, a larger corporate grocery store chain, a medical and dental clinic, two dollar stores and several fast-food chains.

The heart and pulse of the community still lies in its school functions sporting events.

Svecchācāra is an important concept in the Nath Sampradaya.'Svecchācāra' means: acting as one likes, acting without restraint. The word appears to be a combination of three Sanskrit words: sva, cāra adding up to "behaving as one desires" or "in accordance with one's will". John Woodroffe associates it with notions of antinomianism and that it is evident in the Upanishads and Tantras: "Lastly, the doctrine that the illuminated knower of Brahman is above both good and evil should be noted; such a one is a Svechacari whose way is Svechacara or "do as you will". Similar doctrine and practices in Europe are there called Antinomianism; the doctrine is not peculiar to the Tantras. It is to be found in the Upanishads, is in fact a commonly held doctrine in India." Woodroffe goes on to state that: "In Svecchacara there is theoretical freedom, but it is not consciously availed of to do what is known to be wrong without fall and pollution." Svecchācāra is important in the Nath Sampradaya evocation of their realized ideal, of the Avadhuta.

Svecchachara means a way of life where one acts as one wishes and does what is right in one's own eyes. Doing one's own Will; the concluding Sanskrit expression in the Avadhoota Upanishad is "Svecchachara Paro." The term "Paro" means a secret pattern to that action done by one's own Will. In other words, we do our Will but with discretion, not making it too obvious, nor to harm or hurt other people, yet this is a typical Nathism. This term is employed in the closure of the Avadhuta Upanishad; the term'svecchācāra' appears nine times in the Mahanirvana Tantra first translated into the English from Sanskrit by Woodroffe. Svechchhachara, “following one's own will” is evident in the Kali Tantra 8.19. Thelema
