Cool Way to Strip Hydrogen

Facebook X LinkedIn Email
NASHVILLE, Tenn., May 22, 2006 -- A team of researchers has achieved a long-sought scientific goal: using laser light to break specific molecular bonds. The process uses laser light, instead of heat, to strip hydrogen atoms from silicon surfaces. This is a key step in the manufacture of computer chips and solar cells, so the achievement could reduce the cost and improve the quality of a wide variety of semiconductor devices. The technique was developed by Philip I. Cohen at the University of Minnesota, working with Vanderbilt University researchers Leonard C. Feldman, Norman Tolk and Zhiheng Liu along with Zhenyu Zhang from...Read full article
