The Effect of Two MEV Deuteron and Proton Radiation on the Conductivity in N-Type Germanium Dendrite Crystals

Abstract

N-type germanium crystals, both dendrites and ordinary crystals, were irradiated with two MEV deuterons and protons in order to find if any differences in the effects on conductivity of radiation exist between the two types of crystals. The electron reduction rate and the hole production rate was found to be greater by a factor of approximately 2 in the dendrite crystals. The results indicate the formation of acceptor levels associated with the surface. These levels are relatively more important in the more perfect surfaces of the dendrites. A demonstration, showing the possibility of making electronic devices by a simple radiation process, was also conducted.
