Used VARIAN / VEECO GEN II #9232281 for sale

VARIAN / VEECO GEN II is a state-of-the-art molecular beam epitaxy (MBE) equipment designed for high deposition precision and low gas impurity incorporation. It is capable of depositing solid materials onto various substrate types with high accuracy and an excellent resolution. This system is comprised of several components, such as an ultra-high vacuum unit, an effusion cell, and an electron beam evaporator, all of which work together to create the desired film. The ultra-high vacuum machine is composed of several stages of pumps and beam lines, which are used to keep the vacuum at an optimal level for molecular beam epitaxial growth. This tool is accessible through the maintenance panel and is responsible for maintaining a base pressure of 10-7 - 10-8 Torr. The electronic beam evaporator is used to heat and evaporate the material, essentially 'condensing' the molecules on the substrate of choice. This is where closed loop or reactive growth processes[ can be carried out. The effusion cell is used to control the flow of gases and import the chemical precursors necessary for the growth process. This asset is also responsible for precise gas distribution control. It is equipped with a single or dual-channel effusion cell and is capable of using up to two metal or semiconductor sources at a time. This allows for precise control over composition, layer thickness, and deposition rate of the material. VEECO GEN II is also outfitted with an ultra-fine resistive thermal scanning model that ensures precise temperature control over the substrate. This equipment can operate at temperatures ranging from 50 K to 1000 K. Finally, the system is equipped with an electron cyclotron resonance source, which allows for precise control over the ionization of the atoms for incorporation into the film. Overall, VARIAN GEN II is a sophisticated material deposition unit that can provide precise, low-temperature growth of various materials. Its features make it well suited for a wide range of research and development applications.
