高压下石墨超硬相的电阻率测量
In Situ Electrical Measurement on Graphite Superhard Phase under High Pressure
摘要
Abstract
The authors adopted an accurate in situ resistivity measurement method to measure the change of resistivity of graphite with the pressure for cold-compressed graphite in the pressure range of 0-34 GPa via a microcircuit prepared by heavily boron-doped diamond film. The results show that the phase transition of the cold-compressed graphite took place at 15. 1 GPa and 17.9 GPa in the first and second pressure cycles,respectively. The phase can remain at pressure down to 8 GPa.关键词
