In Search of the Perfect Semiconductor Photon Detector
out of 5 stars
19 May 2008 | | Contributor(s):: Peter Y. Yu
Photon detectors have many important applications, such as in heat sensing, digital cameras, solar cells and x-ray and gamma-ray detection. So far, the most common detectors are based on elemental semiconductors , such as Si and Ge. However, they are by no means perfect in tackling some of the...
Nano Carbon: From ballistic transistors to atomic drumheads
14 May 2008 | | Contributor(s):: Paul L. McEuen
Carbon takes many forms, from precious diamonds to lowly graphite. Surprisingly, it is the latter that is the most prized by nano physicists. Graphene, a single layer of graphite, can serve as an impenetrable membrane a single atom thick. Rolled up into a nanometer-diameter cylinder--a carbon...
