内容記述 | We have studied the electronic structure and its changes across the charge-density-wave (CDW) transition in spinel-type CuV2S4 by photoemission spectroscopy and first-principles band-structure calculations. The photoemission spectra show pseudogap-like behavior and the gap size is estimated to be ~90 meV. The large energy scale of the pseudogap compared to the transition temperature and its anomalous temperature dependence implies that the involved interaction is in the strong-coupling regime. The calculated electronic susceptibility χ(q) shows a small peak at q≃11/40[110], which is consistent with the observed wave vector q≃¼[110] characterizing the CDW. This result suggests that Fermi surface nesting is at least partly responsible for the CDW formation | |||||
