Understanding the remarkable excitonic effects and controlling the exciton binding energies in two-dimensional (2D) semiconductors are crucial in unlocking their full potential for use in future photonic and optoelectronic devices. Here, we demonstrate large excitonic effects and gate-tunable exciton binding energies in single-layer rhenium diselenide (ReSe<sub>2</sub>) on a back-gated graphene device. We used scanning tunneling spectroscopy and differential reflectance spectroscopy to measure t ...[more]
