MBE - great box of tricks or mass production tool?

摘要

If anyone ever wanted to know what it is that makes molecular beam epitaxy such a magic process, they need look no futher than the web page for the Max Planck Institute for Solid State Research (http://www.fkf.mpg.de/mbe/). Located in Stuttgart, Germany the MBE Group of the Max Planck Institute for Solid State Research produces, among other things, self-assembled quantum dots using strained InGaAs on GaAs and SiGe on Si. Defect-free, these can be incorporated coherently into host material, as interesting candidates for electronic and optoelectronic applications.
