Used VG SEMICON / OXFORD V100 #293615569 for sale

VG SEMICON / OXFORD V100 is a molecular beam epitaxy (MBE) equipment that is primarily used for the deposition of thin films of semiconductor materials on substrates such as silicon or gallium arsenide. It uses a two-stage source arrangement, with a high-temperature reactant source on top and a low-temperature source on the bottom. The growth chamber is expanded from the main evacuated chamber, and deposition take place at pressures of ~3×10^-7 torr, under vacuum. In this system, there are two hemispheric lenses which focus the molecular beams onto the sample surface, and heating/cooling coils for both reactant sources and the growth chamber. OXFORD V100 is equipped with a number of instruments for process control, such as a pressure measurement unit, an in-situ quartz crystal microbalance (QCM), an oxygen getter machine, an in-situ reflectometer, and a quartz crystal thermometer. The in-situ QCM is used to measure the mass deposition rate and composition of thin films, while the in-situ reflectometer is used to monitor the surface morphology. The oxygen getter tool can be used to maintain a low oxygen concentration in the growth chamber to prevent oxidation of the semiconductor films during deposition. The quartz crystal thermometer can be used to monitor both the reactant source and chamber temperatures. VG SEMICON V100 is mainly used for growing films of semiconductor materials such as silicon and gallium arsenide by MBE. These films are usually very thin, typically only a few atomic layers thick, and require very precise control of growth parameters to ensure proper growth of the films. V100 is also suitable for growth of films of other materials such as aluminum gallium arsenide, gallium nitride and aluminum oxide. In conclusion, VG SEMICON / OXFORD V100 is a sophisticated MBE asset that can be used for deposition of ultra-thin films of semiconductor and other materials. It is equipped with a range of instruments to ensure precise process control, which is required for the growth of high-quality films.
