Electrical Control of Excitons in Bare MoSe <sub>2</sub> and MoSe <sub>2</sub> /NbSe <sub>2</sub> Heterostructures
, the heterostructure exhibits a pronounced thermal dependence of the enhancement factor, implying that the exciton lifetime dominates over interfacial transfer processes. Our findings demonstrate reversible, electric-field-driven PL control at a TMDC/metal interface, providing a pathway to electrically tunable light emission and improved contact engineering in two-dimensional optoelectronic devices.
