A Primer on Scanning Tunneling Microscopy (STM)
out of 5 stars
04 Apr 2006 | | Contributor(s):: Ron Reifenberger
Scanning Probe Microscopes and their remarkable ability to provide three-dimensional maps of surfaces at the nanometer length scale have arguably been the most important tool in establishing the world-wide emergence of Nanotechnology. In this talk, the fundamental ideas behind the first scanning...
Carbon Nanotechnology: Scientific and Technological Issues
24 Feb 2008 | | Contributor(s):: Joe Lyding
Carbon nanotechnologies based on single-walled carbon nanotubes (SWNTs) and graphene (a single atomic layer of graphite) are being pursued for a wide range of technological applications ranging from chemical sensing to post-silicon nanoelectronics. A common thread is the need to atomistically...
