Abstract

MoSe2/WSe2 transition metal dichalcogenide heterostructures host spatially-indirect interlayer excitons (ILX) following interlayer charge transfer (ICT). We perform ultrafast transient absorption spectroscopy directly probing the ILX formation time and find it to be significantly longer than ICT.
