Renormalization of the band gap in 2D materials through the competition between electromagnetic and four-fermion interactions
Luis Fernández, Van Sérgio Alves, Leandro O. Nascimento +3
Recently the renormalization of the band gap , in both WSe and MoS, has been experimentally measured as a function of the carrier concentration . The main result esta…
