摘要: 本文首次报道一种用于高压下电磁现象研究的两级非磁性超高压装置,描述了其结构原理和设计概要。这一装置目前达到的最高调试压力为28kbar,这是完全流体静力学的压力。利用本装置,已在0—25kbar的压力范围内进行了锑化铟、锗、碲镉汞等的电阻率和霍耳系数随压力变化的测量,对于这些材料能带结构和迁移率特性随压力变化,已获得令人满意的结果。
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.
