During one stage of follow-up efforts by Brattain and Bardeen to counteract the effect of the surface states, a set-up was devised which led to the accidental discovery of the point-contact transistor, a completely different device from the one originally contemplated. Prior work on germanium ...
It has had profound impact on the way we live and the way we work. The first part of this paper covers the events that led to the discovery of the transistor effect and the invention of the point contact transistor in December of 1947. It continues with the development of the theory of...
In the late 1940s at Bell Labs a raft of teams were looking at different areas of semiconductor technology. Spurred on by the invention of the point contact transistor a number of other developments were announced and although they are not as widely publicised, they also had a major impact ...
Already in the 1920's, scientists understood how to make a two terminal device by making a point contact between a sharp metal tip and a piece of semiconductor crystal. These point-contact diodes were used to rectify signals, and make simple AM radio receivers (crystal radios). However, it...

How do we invent something that conveys the true meaning of what we intend to give to the the other parties so that they understand what we really mean. How can understanding of all of the communication we are inundated with be crystal clear? [/quote] Carl, you have a very good po...
However, if such a CNT is contacted by metal contacts, a transits resistance in the kΩ range develops at each contact point. In semicon-conductive CNTs, the specific resistance depends on the voltage applied, the resistance in the range of about −0.5 V to 0.5 V being several MΩ ...
