Chemical thermodynamic (non) epitaxy


Using the word "revolutionary" in the context of semiconductor materials is both interesting and dangerous. According to University of Maryland researchers (www.newsdesk.umd.edu/scitech/release.cfm?ArticleID=2106 and published in the journal Science 26 March 2010:Vol. 327. no. 5973, pp. 1634 - 1638) a completely new way to produce high quality semiconductor materials, "critical" for advanced microelectronics and nanotechnology, has been devised. The team has created a process that uses chemical thermodynamics to produce, in solution, a broad range of different combination materials, each with a shell of structurally perfect mono-crystal semiconductor around a metal core. Early days, but an HBT in a test tube?
