Abstract

We report measurements of the structural and transport properties of ZrTe2 single crystal and find this to be characteristic of a semimetal with hexagonal crystalline phase. We consider that this semi metallic behavior arises from a small overlap of the tellurium p valence band and the zirconium d conduction band. Thermoelectric power shows the diffusion of holes are greater compared to electrons from hot to cold end. Measurement of the resistivity shows an increase in the band overlap and carrier concentration with pressure. Surface microstructure analysis done on various samples of ZrTe2 shows the presence of step growth..
