MOLECULAR BEAM EPITAXIAL MATERIALS FROM FUNDAMENTAL RESEARCH TO PRODUCTION

We describe the successful development of molecular beam epitaxy(MBE) from experiment to production,an excellent example for the understanding of the whole progress of high technology development.Theoretical physicists proposed the superlattice concept and predicted its properties,then experimental physicists prepared different heterojunction structures and superlattices with high electron mobility or unique optical properties,after which device physicists fabricated several important devices and circuits,such as microwave and millimeter wave devices,PHEMTs and quantum well lasers,which further promoted MBE development.The demand of MBE materials in cellular phones and the internet,wide band communication,anti|collision radar for automobiles and high efficiency solar cells have brought great opportunities for MBE production.
