Abstract

We have grown pure, Co- and V-doped Ge bulk single crystals using the vertical gradient solidification method. We measured electrical resistivities, magnetoresistances (MRs) and Hall coefficients of V_0.015Ge _0.985 and Co_0.02Ge_0.98 single crystals. The resistivities rapidly increased at low temperature, which might be used for cryogenic thermometer. The MR ratios of V_0.015Ge_0.985 and Co_0.02Ge_0.98 are 130 and 90% at 77 K in the field of 5 T, respectively.
