Description:
Author(s): Selene Mor, Marc Herzog, Denis Golež, Philipp Werner, Martin Eckstein, Naoyuki Katayama, Minoru Nohara, Hide Takagi, Takashi Mizokawa, Claude Monney, and Julia Stähler We report on the nonequilibrium dynamics of the electronic structure of the layered semiconductor Ta 2 NiSe 5 investigated by time- and angle-resolved photoelectron spectroscopy. We show that below the critical excitation density of F C = 0.2 mJ cm − 2 , the band gap narrows transiently, while it is enhance... [Phys. Rev. Lett. 119, 086401] Published Wed Aug 23, 2017
