Centrifugal liquid-phase epitaxy is used commercially to make thin layers of silicon, germanium, and gallium arsenide. [17] [18] Centrifugally formed film growth is a process used to form thin layers of materials by using a centrifuge. The process has been used to create silicon for thin-film solar cells [19] [20] and far-infrared ...
This was for a device grown on a GaSb substrate by organometallic vapour phase epitaxy (OMVPE). Devices have been grown by molecular beam epitaxy (MBE) and liquid phase epitaxy (LPE). The internal quantum efficiencies (IQE) of these devices approach 90%, while devices grown by the other two techniques exceed 95%. [30]
Ramp - The furnace is heated from an initial temperature to a maximum temperature, where the growth forms a complete liquid solution. Dwell - The furnace is maintained at the maximum temperature to homogenize the solution. Cool - The furnace is cooled to a desired temperature over a specified rate or time. Removal - The growth is removed from ...
Pendeo-epitaxy is mainly performed from the vapor phase via MOCVD and HVPE, and initially is used for growing gallium nitride (GaN) microelectronic device structures. In the case of GaN material system, LEO and PE technology was initiated in the late nineties and early 2000s in Prof. R.F. Davis group at NCSU.
Metalorganic vapour-phase epitaxy (MOVPE), also known as organometallic vapour-phase epitaxy (OMVPE) or metalorganic chemical vapour deposition (MOCVD), [1] is a chemical vapour deposition method used to produce single- or polycrystalline thin films.

Thermal laser epitaxy: a continuous-wave laser evaporates individual, free-standing elemental sources which then condense upon a substrate. Sputter deposition: a glow plasma discharge (usually localized around the "target" by a magnet) bombards the material sputtering some away as a vapor for subsequent deposition.
Hydride vapour-phase epitaxy (HVPE) is an epitaxial growth technique often employed to produce semiconductors such as GaN, GaAs, InP and their related compounds, in which hydrogen chloride is reacted at elevated temperature with the group-III metals to produce gaseous metal chlorides, which then react with ammonia to produce the group-III nitrides.
