Profile: E-Science, Inc. specializes in providing components for deposition reactors. Our products include effusion cells, substrate heaters, specialty valved sources and accessories for MOCVD & MBE reactors. Titan™ Effusion Cell uses technology for evaporating Ga or In source material. It utilizes a special two-piece graphite crucible that lowers defect counts, improves uniformity and reduces shutter related flux transients. Dual filament effusion cell includes dual filament and dual thermocouple, which allows the users to tailor the thermal profile of the cell. Substrate heaters are available for both MBE and MOCVD reactors. The configurations available include heaters for nitride applications, oxide applications, and more standard heaters for common material systems.
