Abstract

In this article, we review some recent advances in the studies of the pressure-induced structural changes in liquid arsenic and liquid IV-VI compounds. For liquid As, the A7-like local structure has been experimentally observed and attributed to a "Peierls distortion in the liquid state". Most recently the suppression of the distortion has been observed at high pressures. We also observed the similar pressure dependence in liquid GeS, GeSe, and GeTe, where their structures are distorted at low pressures. We describe the pressure-induced suppression of Peierls-type distortion in these liquids, and show the differences between liquid and crystalline states.
