Nanometer vacuum tube talk
« on: 5 Feb 2013, 01:33 am »
For those of you in the SF Bay area, this sounds like it could be an interesting lecture.  It's about the possibility of creating a new generation of vacuum tubes based on nanotechnology.

Nanometer scale vacuum tubes are the topic for the February 19th IEEE SFBA Nanotechnology Council noon time seminar.
 
What could nanoscale vacuum tubes possibly be used for? Maybe high fidelity implantable hearing aids for some of us. How about low noise amplifier for cell phone earrings? Detecting space alien utterances?- could be why NASA is so interested in them. Join in and ask the expert.

TITLE: CMOS Compatible Nanoscale Vacuum Tube
SPEAKER: Dr. Jin-Woo Han, Research Scientist, NASA AMES Research Center

ABSTRACT:
Vacuum tubes had been the major workhorse in electronics before the commercial silicon transistor emerged in 1960’s. The vacuum tube performs rectifying and amplifying functions by utilizing the electrons movement through a free space. However, the vacuum tube is hard to integrate, heavy, fragile, and energy consuming. The solid-state transistor overcame these limitations because it is easy to integrate, light, reliable, and energy efficient. Compared to the vacuum tube, however, the transistor has low gain and is sensitive to noise and distortion as the carriers travel through silicon lattices. Therefore, the vacuum tubes are still used in a premier sound systems and baseband broadcasting stations.
A nanometer scale vacuum tube can provide the advantages of both vacuum tube and transistor. The nano vacuum tube can be fabricated and integrated with semiconductor process technology, providing compactness as well as high performance. Furthermore, while transistor operation in extreme conditions such as high temperature and radiation are problematic, the nano vacuum tube can operate well in these environments since it uses a vacuum channel. This implies that the nano vacuum tube might be exploited even for automobile and space applications. In this talk, the nanoscale vacuum transistor will be discussed.

Probably - it's about a 10 minute drive from where I work so I should be able to get over there.
