The Nanotechnology R(evolution)
Charles Tahan
Nanotechnology as a social concept and investment focal point has drawn much attention. Here we consider the place of nanotechnology in the second great technological revolution of…
Identifying Nanotechnology in Society
Charles Tahan
Manufacturing materials and systems with components thousands of times smaller than the width of a human hair promises vast and sometimes unimaginable advances in technology. Yet t…
Controllable valley splitting in silicon quantum devices
Srijit Goswami, K. A. Slinker, Mark Friesen +10
Silicon has many attractive properties for quantum computing, and the quantum dot architecture is appealing because of its controllability and scalability. However, the multiple va…
Quantum phase transitions of light
Andrew D. Greentree, Charles Tahan, Jared H. Cole +1
Recently, condensed matter and atomic experiments have reached a length-scale and temperature regime where new quantum collective phenomena emerge. Finding such physics in systems…
Valley Splitting Theory of SiGe/Si/SiGe Quantum Wells
Mark Friesen, Sucismita Chutia, Charles Tahan +1
We present an effective mass theory for SiGe/Si/SiGe quantum wells, with an emphasis on calculating the valley splitting. The theory introduces a valley coupling parameter, ,…
