float-zone process
1Float-Zone Process — In reference to solar photovoltaic cell manufacure, a method of growing a large size, high quality crystal whereby coils heat a polycrystalline ingot placed atop a single crystal seed. As the coils are slowly raised the molten interface beneath …
2Float-zone silicon — is a high purity alternative to silicon grown by the Czochralski process. The concentrations of impurities, such as carbon and oxygen, are extremely low. Impurities such as nitrogen, which are thought to bring about an improvement in mechanical… …
3float-zone silicon — noun a very pure form of crystalline silicon, made by the Czochralski process …
4Zone melting — is a method of separation by melting in which a molten zone traverses a long ingot of impure metal or chemical. In its common use for purification, the molten region melts impure solid at its forward edge and leaves a wake of purer material… …
5zone melting — a process of purifying any of various metals and other materials, as germanium or silicon, by passing it in bar form through an induction coil. Also called zone refining. Cf. cage zone melting. [1955 60] * * * Any of a group of techniques used to …
6Czochralski process — The Czochralski process The Czochralski process is a method of crystal growth used to obtain single crystals of semiconductors (e.g. silicon, germanium and gallium arsenide), metals (e.g. palladium, platinum, silver, gold), salts, and synthetic …
7Hayward Fault Zone — The Hayward Fault Zone is a geologic fault zone capable of generating significantly destructive earthquakes. About 60 kilometers long, it lies mainly along the western base of the hills on the east side of San Francisco Bay. It runs through… …
8Oceanic physical-biological process — Sea water is 827 times denser than air Due to the higher density of sea water (1,030 kg m 3) than air (1.2 kg m 3), the force exerted by the same velocity on an organism is 827 times stronger in the ocean. When waves crash on the shore …
9Separation process — In chemistry and chemical engineering, a separation process, or simply a separation, is any mass transfer process used to convert a mixture of substances into two or more distinct product mixtures, at least one of which is enriched in one or more …
