David M. Cardamone, from the Department of Physics, Simon Fraser University, and Charles A. Stafford and Sumit Mazumdar Department of Physics, from the Department of Optical Sciences, University of Arizona talk in the SPIE Newsroom about a novel kind of transistor. They claim that their device is not based on field-effect, but on quantum interference. They show some results obtained using a benzene molecule as device, and, frankly, the results are not bad at all. However, I have my doubts that this can be practical in a medium range, because many problems (mainly the interconnections, from my point of view) are left open. Moreover, I'd like to see a digital gate made using these devices. Or, better, an analog amplifier. That could be a real test.
