External screening and lifetime of exciton population in single-layer ReSe${}_2$ probed by time- and angle-resolved photoemission spectroscopy

Klara Volckaert, Byoung Ki Choi, Hyuk Jin Kim +7

The semiconductor ReSe${}_2$ is characterized by a strongly anisotropic optical absorption and is therefore promising as an optically active component in two-dimensional heterostruct…
