On the transformation of ß-particle energies to electric energy in germanium crystals with p-n junctions
Tóm tắt
We present the results of an investigation performed in 1955 on the transformation of the energy of fast electrons into electric energy by germanium crystals with p-n junctions, as well as data on the efficiency of this transformation and its dependonce on the absorbed radiation flux and total dose. It is found that the basic factor reducing the efficiency of transformation is the increase of the recombination rate of electrons and holes on recombination levels of structural defects arising as a result of the irradiation. Changes in the equilibrium electric conductivity and carrier mobilities play a secondary role. A method is indicated for reestablishing the initial properties of crystals by heating them. Ionization curves are given for monoencrgetic electron beams in germanium.
