Development of a Knudsen cell for molecular beam epitaxial growth of GaAs films in the microgravity environment
Abstract
A Knudsen cell for gallium deposition in an on-orbit molecular beam epitaxy laboratory is under development. This sub-component of a major NASA system is based upon ground-based designs; however, it incorporates several features which address some of the problems associated with the microgravity environment. The paper highlights the hardware development with use of video footage from the recent KC-135 flight and includes some analytical considerations.
