Thermo-radiative stability of the materials based on solid alloy of silicon-germanium n- and p-type in reactor neutron field

N- and P-type samples of silicon-germanium solid alloy with specific resistance (1/2)x10-3Ωcm doped with mixture of natural phosphorus and boron during irradiation in the active core of the WWR-M reactor at temperature of (200-500)0C were studied. The dose dependence of the specific resistance and thermo-emf of the samples based on silicon-germanium solid alloy was described in frameworks of the effective medium theory. In accordance with this theory the clusters defects are considered as dielectric insertions in conducting sample matrix. 10 refs.; 4 figs.; 2 tabs. (author)
