We study the optical and electronic properties of low-dimensional quantum materials and their heterostructures. Combining optical spectroscopy, scanning photocurrent measurements, and electronic transport, we investigate excitons, correlated electronic states, and emergent quantum phenomena.
Our research spans two-dimensional semiconductors and moiré heterostructures, with a focus on light–matter interactions, exciton physics, and correlated electronic states.
27 October 2026Congratulations to Xiangzhi Hong on his PRL publication!In a graphene/bilayer MoS₂ heterostructure, the team used interlayer-exciton spectroscopy to identify a quantum-capacitance-induced residual Stark response and measure graphene’s local chemical potential.
