摘要

Abstract

Emerging photo-induced excitonic processes in transition metal dichalcogenide (TMD) heterobilayers

e.g.

interplay of intra- and inter-layer excitons and conversion of excitons to trions

allow new opportunities for ultrathin hybrid photonic devices. However

with the associated large degree of spatial heterogeneity

understanding and controlling their complex competing interactions in TMD heterobilayers at the nanoscale remains a challenge. Here

we present an all-round dynamic control of interlayer-excitons and -trions in a WSe

/Mo

0.5

heterobilayer using multifunctional tip-enhanced photoluminescence (TEPL) spectroscopy with

20 nm spatial resolution. Specifically

we demonstrate the bandgap tunable interlayer excitons and the dynamic interconversion between interlayer-trions and -excitons

through the combinational tip-induced engineering of GPa-scale pressure and plasmonic hot electron injection

with simultaneous spectroscopic TEPL measurements. This unique nano-opto-electro-mechanical control approach provides new strategies for developing versatile nano-excitonic/trionic devices using TMD heterobilayers.
