摘要：
The Fermi surface of the layered charge-density-wave compound 2H-TaSe2 is measured by angle-resolved photoemission as a function of temperature. A surprising Fermi-surface topology and a Fermi-surface branch-dependent charge-density-wave gap are found. In the charge-density-wave state band hybridization effects are strong and responsible for kinks in the band dispersions at relatively high binding energy. The implications of the results on the charge-density-wave mechanism are discussed.
