The Single-Atom Transistor: How It Was Created and What It May Mean for the Future

Published on


Professor Gerhard Klimeck will be coming to speak on his research with single atom transistors.

The end of Moore’s law has been falsely predicted repeatedly over the past 20 years, while Silicon technology has been driven to seemingly unlimited miniaturization. One foundational limit of size downscaling, however, will be hard to overcome – the discreteness of the underlying atomic system. Let’s assume cost and manufacturability issues can be overcome: Can one reach such atomic limits? Can one make wires that are say 4 atoms wide and 1 atom tall and still provide Ohmic conductivity? Can one connect such atomically thin wires to a single impurity atom embedded in Silicon? If you can build such a thing, how would you know that it is single impurity atom? What modeling approaches are needed? How can such modeling software be disseminated widely? This presentation will address these questions through experimental and theoretical results of our recently demonstrated “Single Atom Transistor” and overview briefly.


Gerhard Klimeck Gerhard Klimeck is a Professor of Electrical and Commuter Engineering at Purdue University. In the past 19 years at Texas Instruments, NASA/JPL, and Purdue he has been the driving force for the Nanoelectronic Modeling Tool Suite (NEMO). He also leads (TEDxPurdueU-Gerhard-Klimeck) as a director in the service of nanoelectronic simulation and education on the web, serving over 240,000 users. Gerhard is a fellow of the IEEE, the American Physical Society, and the Institute of Physics.
