| Abstract: | We report here for the first time a two stage nonmagnetic high pressure equipment foi studying various transport phenomena. The structure and the principle of the design are described. the experimental results are presented. A completely hydrostatic pressure of 28 kbar is obtained. With this equipment, the resistivity and Hall coeffecient for Ge, InSb and HgCdTe have been measured under pressure up to 25 kbar. The energy gaps and the carrier mobilities as functions of pressure for these materials have been determined, the results are in good agreement with those of other experiments. |
