## Interplay between electron-electron interaction and electron-phonon coupling near the Fermi surface of 1T-TaS2

### In: Physical Review B, 2000, vol. 62, no. 7, p. 4277-4287

We present a detailed high-resolution angle-resolved photoemission study of the electronic band structure of the room-temperature quasicommensurate charge-density-wave phase of 1T-TaS2. In particular, we show that no crossings of the Fermi level are visible in the complete Brillouin zone, indicating that an electron-electron correlation-induced pseudogap in the Ta 5d... More
