Molecular beam epitaxy system.
VARIAN / VEECO GEN 200 is a molecular beam epitaxy (MBE) equipment designed to promote a variety of thin film deposition processes, including but not limited to the growth of III-V compounds. It consists of a high-vacuum chamber, a heated substrate holder, and a multi-gun effusion cell arrangement. The chamber is equipped with auxiliary components for purging, thermal and mechanical shielding, and introduction of dopant gases. The main features of this MBE system are its two independently-controlled effusion cells, dual resistance-heated substrate holders, and the ability to switch from two- to four-guns on the fly. The substrate temperature can be set and maintained in the range of 10°C to 1000°C with an accuracy or ±5°C. The high vacuum chamber has a background pressure of 5.0x10-10 Torr and a throughput of 6.0 liters per second. For sample purging and charge neutralization purposes, the unit is equipped with a gas shutter, electrostatic ion-neutralizer, and an enclosed evaporator. The main purpose of VEECO GEN 200 is to produce homogeneous and high-quality thin films. It uses an advanced effusion cell control machine to ensure precise control of source temperatures which in turn results in a steady mass transfer rate of source material. This tool is highly capable of producing material growths with smooth and planar surfaces, allowing for precise doping concentrations. With its advanced and programmable design, VARIAN GEN 200 provides the user with the flexibility to do both multi-layer and single-layer deposition. This allows users to produce samples with superior thin film properties for both research and industrial applications. In addition, this MBE asset is equipped with a sophisticated data acquisition model which enables the user to monitor various growth conditions in real-time. The equipment also has an advanced Graphical User Interface (GUI) which simplifies the control and operation of the system. Overall, GEN 200 is a highly capable MBE unit with its dual independent effusion cells, temperature control, and gas purging mechanisms. With its sophisticated control machine and high degree of precision, this tool can produce a range of thin film materials with superior quality and homogeneity.
