Abstract

Combined photoluminescence and Raman spectroscopies of WS₂/graphene heterostructure through pump-power and temperature controls show that redshift of photoluminescence is mainly caused by pump induced heating, while linewidth-broadening has contributions from both heating and carrier transfer.
