EARLY TRANSISTOR HISTORY AT RCA Jacques Pankove Oral History –  Continued
Here are samples of the first developmental alloy junction transistors that were built at RCA labs, using the techniques developed by Pankove, Mueller, Law and Armstrong.  The type TA153 was built in the few thousands on a pre-production line set up at the Harrison plant, and were used to develop circuit applications, such as radios, to demonstrate the possibilities of this new technology.	The scan shown above is a section of a patent granted to Dr. Pankove that relates to his early work at RCA on alloy junctions transistors. As described in the Oral History, Dr. Pankove hypothesized that the current gain of an alloy transistor was related to the relative sizes of the emitter and collector indium dots used to construct the transistor – the comparison chart shown on this patent provides supporting data.  Also, as mentioned in the Oral History, work on this patent led to the nickname used by the RCA patent department of “Big-dot-small-dot Pankove”! ______________
