Exploring the Charge Density Wave phase of 1-TaSe: Mott or Charge-transfer Gap?
C. J. Sayers, G. Cerullo, Y. Zhang +8
1-TaSe is widely believed to host a Mott metal-insulator transition in the charge density wave (CDW) phase according to the spectroscopic observation of a band gap that exte…
Current driven insulator-to-metal transition without Mott breakdown in CaRuO
