IBM Makes Graphene at 30 GHz and Potential of 100 Ghz to 1 Terahertz Graphene

MIT Technology Review – IBM has created prototype graphene transistors made from atom-thick sheets of carbon, operate at 100 gigahertz–meaning they can switch on and off 100 billion times each second, about 10 times as fast as the speediest silicon transistors. IBM has created graphene transistors that leave silicon ones in the dust. The prototype …

Nanodragster shows progress to Better Molecular Machines

Previously nanocars were created and now there is a somewhat faster nanodragster. The Nanodragster operates at lower temperatures and rolls more easily. It was created by James Tour and his research colleagues. The synthesis and imaging by scanning tunneling microscopy of a mixed wheeled nanovehicle composed of a p-carborane small-wheeled short front axle and a …

Philip Moriarty discusses Molecular Nanotechnology Validation experiment plans

On the Center for Responsible Nanotechnology blog comments, Philip Moriarty discusses his plans for testing the viability of positionally-controlled atom-by-atom fabrication of diamondoid materials as described in the Freitas-Merkle minimal toolset theory paper. A combination of low temperature tuning fork (Qplus) AFM, STM, and tunnelling spectroscopy (dI/dV and d2I/dV2, i.e. inelastic tunnelling spectroscopy) will be …
