The early 1950s designer had to work with germanium point ... the problem that there is a voltage drop across each gate. Thus if you daisy-chain a series of diode gates you will find that with ...

These home made transistors sacrifice a point contact diode to get the small chip of germanium ... and is then secured with a drop of beeswax. A slight surprise comes in how point contact ...

One of the graduate students, Seymour Benzer, accidentally discovered that a crystal of germanium -- a semiconductor which was not well understood at the time -- could withstand higher voltage ...
