Realizing artificial quantum systems with regularly arranged electrons in semiconductors to simulate physical properties has long been a dream in mesoscopic physics. Recently, such systems have been realized using nanoscale-period moiré superlattices formed by interference patterns in two-dimensional materials. These systems exhibit a wide range of quantum phenomena, including strongly correlated electron states, superconductivity, magnetism, and topological properties. Understanding and controlling the behavior of these novel quantum systems at a microscopic level can lead to the development of metamaterial science at the nanoscale.

Our laboratory focuses on the study of moiré superlattices in semiconductor two-dimensional materials, investigating their electronic properties from both macroscopic quantum phenomena and microscopic quantum device physics. In particular, we aim to reveal quantum properties and device physics through precise electrical control and optical excitation. Additionally, we are developing new methods to explore electronic properties using excitons as probes.
