Irradiation Effects in PbSnTe.
Abstract
The electrical properties of Pb(1-x)Sn(x)Te have been measured before and after irradiation and during isochronal annealing after irradiation for samples with a nominal value of x = 0.2 and different initial hole densities. For two samples that were initially degenerate at 78K, the hole density decreased with electron and fission neutron irradiation. For a zinc-diffused sample that was initially nondegenerate at 78K, electron irradiation caused an increase in hole density. The heavily doped samples remained p-type over the full range of temperature measurements, whereas the lower-density sample converted to n-type at higher temperatures. Possible models are proposed to explain these results. Theoretical calculations of lattice mobility have been made and are compared to the measured mobilities. The theoretical amount of radiation energy that goes into displacement damage in PbSnTe has been calculated for electrons of various energies and for a fission neutron spectrum. (Author)
