Abstract:

A study is being conducted to understand the nature of the negative resistance phenomena in compensated germanium during impact ionization of majority carriers bound to impurity sites at 4.2 degrees Kelvin. The program is organized along two lines. The theoretical part is concerned with formulating an acceptable model of the phenomena and solving the pertinent equations which predict the devices operation with regard to majority and compensating impurities. The other part of the program is concerned with growing compensated crystals of known impurity concentrations and measuring the electrical characteristics of liquid helium temperature. Attention is given to the problem of achieving radial uniformity in the Czochralski process. Author
