Thought for the month

“You cannot have freedom without a rule of law ... and if you don't have it, what you tend to get is corruption and that is death to freedom, it's death to truth, it's death to honour, it's death to democracy.”

Margaret Thatcher, 1 October 1996.

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?
