Charge-Density-Wave induced modifications to the quasiparticle self-energy in 2H TaSe2

T. Valla, A. V. Fedorov, P. D. Johnson +3

The self-energy of the photo-hole in 2H-TaSe2 is measured by angle-resolved photoemission spectroscopy (ARPES) as a function of binding energy and temperature. In the charge-densit…
