OPTICAL INVESTIGATIONS OF DEFECT ENERGY LEVELS IN n-TYPE GERMANIUM IRRADIATED WITH REACTOR FAST NEUTRONS
Quenching of photoconductivity was used to investtgate the properties of defect energy levels in n-type germanium irradiated with fast neutrons from a reactor. The quenching curve obtained (quenching vs wavelength of the external illumination) shows distinct maxima and bumps, which can be explained on the basis of the general accepted model of defect energy levels in fast-neutron- irradiated germanium. However, for the first time the distance between the level 0.2 ev, below the conduction band, and the level 0.07 ev, above the valence band, was measured in a direct way. These experiments show also that the quenching effect in neutron irradiated n-type germanium is connected with hole-trapping properties of the defect energy level 0.18 ev above the valence band.
