Folded superstructure and degeneracy-enhanced band gap in the weak-coupling charge density wave system 2H−TaSe2
Using high-resolution angle-resolved photoemission spectroscopy (ARPES), we have mapped out the reconstructed electronic structure in the commensurate charge-density-wave (CDW) state of quasi-two-dimensional transition metal dichalcogenide 2H-TaSe2. The observation of the fine structure near Brillou...
