"NANOTECH: Oregon prof: Wires beat tubes in nano world"
With so many stories heralding the merits of carbon nanotubes as the channels of next-generation nanoscale transistors, you'd think the case was closed. Not so, say researchers here who claim nanowires can create better nanoscale transistors � ones that can be placed more accurately, can use application-specific doping and can be more easily integrated with traditional silicon processing. "Our most recent results show how to grow nanowires in precisely the places you want them on silicon wafers. Nanowires offer many advantages over nanotubes, such as the ability to dope them in different well-understood ways for different applications," said EE professor Rajendra Solanki at Oregon Health and Science University.
