摘要：
The results of Shubnikov-de Haas (SdH) oscillation measurements on p-CoSb3 single crystals are presented. The values of the cyclotron effective mass were determined. It was found that the effective mass increases from 0.11 m(0), to 0.15 m(0) with increasing hole concentration, indicating a non-parabolicity of the valence band of CoSb3. Using the two-band Kane model a band-edge effective mass of m(n)/m(0) = 0.050 +/- 0.002 and an energy gap E-g = 35 +/- 2 meV were estimated. (C) 1999 Elsevier Science B.V. All rights reserved.
