Abstract:
We have been fabricating nanoscale vacuum tubes over the last three years using entirely and exclusively silicon technology. Vacuum is superior to any semiconductor in terms of electron transport, in addition to being immune to all radiations. We have combined the best of vacuum transport and silicon technology to fabricate surround gate nanoscale vacuum transistors on 8 ' wafers with a channel dimension of 50 nm. These vacuum transistors, operating at a drive voltage of only 2 V, which is remarkable for vacuum devices, have the potential for THz electronics and several other applications.
This talk will also provide an overview of our recent activities in printable electronics including gas sensors, antennas and triboelectric nanogenerators. To enable a one-step printing without the need for post-deposition thermal treatment, we have developed an atmospheric pressure plasma jet printing technology. This is an alternative to inkjet printing for depositing conducting, semiconducting, insulating and other materials on a variety of flexible substrates.
