(PhysOrg.com) -- University of Wisconsin-Madison researchers have achieved a nanoscale laser structure they anticipate will produce semiconductor lasers in the next two years that are more than twice as efficient as current continuous-wave lasers emitting in the mid-infrared. http://www.physorg.com/news180032976.html Physics Mon, 14 Dec 2009 18:00:20 EST news180032976 (PhysOrg.com) -- A new generation of ultrasmall transistors and more powerful computer chips using tiny structures called semiconducting nanowires are closer to reality after a key discovery by researchers at IBM, Purdue University and the University of California at Los Angeles. http://www.physorg.com/news178459486.html Nanotechnology Thu, 26 Nov 2009 14:00:05 EST news178459486 (PhysOrg.com) -- One of the issues hindering the development of medical electronic devices capable of being implanted in the human body is the lack of suitable materials. Most semiconducting materials are stiff and brittle, while human tissue is soft and pliable. Scientists at the University of California, Los Angeles (UCLA), appear to have taken a key step forward in implantable electronics research. http://www.physorg.com/news160652779.html Nanotechnology Mon, 04 May 2009 10:48:24 EST news160652779 (PhysOrg.com) -- A research group in Germany has discovered a semiconducting material that can switch its semiconducting properties -- turning from one type of semiconductor to another -- via a simple change in temperature. This intriguing behavior may make the material useful in efforts to create better performing integrated circuits, which form the backbone of almost all electronic devices. http://www.physorg.com/news152534700.html Physics Fri, 30 Jan 2009 10:46:08 EST news152534700 (PhysOrg.com) -- Using a simple chemical process, scientists at Cornell and DuPont have invented a method of preparing carbon nanotubes for suspension in a semiconducting "ink," which can then be printed into such thin, flexible electronics as transistors and photovoltaic materials. http://www.physorg.com/news150650570.html Nanotechnology Thu, 08 Jan 2009 15:22:50 EST news150650570
