Halogen transport of molybdenum arsenides and other transition metal pnictides
Abstract
Crystals of MoAs 2, Mo 2As 3, and Mo 5As 4 have been grown by chemical transport using halogens as the transport agents. The variation of the transport rate with halogen, halogen concentration, temperature and temperature gradient has been studied. Total pressure, optical/UV absorption, and vapour analysis measurements have been employed to study the equilibrium vapours of the Mo/As/Br system up to 1175 °K. The arsenic trihalide is a major vapour component in this system and probably in other transition metal pnictides/halogen systems. The transport mechanism differs from that found in previously studied systems.
