摘要：

The electronic structure of high-quality 1T-TiSe2 has been investigated using angle-resolved synchrotron ultraviolet photoemission. Occupied Ti d states are clearly observed in small pockets around the zone-edge centers and are found to be roughly degenerate with the highest-lying Se p states at. The results are relevant to various explanations of the 2a0×2c0 lattice instability in this material, including a possible excitonic electron-hole interaction. © 1978 The American Physical Society.
