Relaxation and transfer of photoexcited electrons at a coplanar few-layer 1 T′/2H-MoTe2 heterojunction

Abstract

Heterostructures can reveal interesting and unexplored physics at the material interface. Here, the authors use time-resolved photoemission electron microscopy to investigate the photoexcited electron dynamics at a heterostructure interface composed of two polytypes of MoTe2.
