Molecular Beam Epitaxy for Research on Quantum Well Structures.

Proposed was the purchase of a Molecular Beam Epitaxy MBE system as the key instrument to establish a coherent, interdisciplinary research program in the area of quantum well structure research. The system will have two growth chambers instead of the proposed single chamber. One is a conventional solid source MBE systm and the other is the novel gas source MBE with organometallic sources. Our growth capability is thus enhanced by the acquisition of a system in which pioneering materials research can be performed. Custom modifications to the growth systems have been incorporated to allow non-standard, in situe MBE analytical studies to be performed. It is believed that our MBE system is at present unique in a US university. These programs will concentrate on basic material growth kinetics in gas source MBE, heterojunction and multi-quantum well MQW electronic and optical properties and devices for integrated optoelectronics.
