Our research focuses on exploring the microscopic nature of quantum materials and their device applications. In our approach, we combine novel 2D van der Waals heterostructure device fabrication techniques with cryogenic scanning probe measurements, designed to access the atomic-scale electronic structure and local physical properties of quantum phases in 2D materials Van der Waals (vdW) heterostructures, assembled layer by layer from two-dimensional materials, overcome conventional materials’ constraints, offering unprecedented access to new material platform. This enables precise engineering of quantum properties through the interaction between atomic layers. Our research focuses on the development of novel vdW systems, their integration into devices via nano-fabrication, and their study at extreme environment, where quantum mechanical effects dominate. We study their electric/magnetic/topological properties under varying conditions—such as magnetic fields, carrier densities, and electric fields—to identify unconventional quantum order of electrons. Furthermore, we utilize scanning probe microscopy (SPM) to observe electron behavior at the atomic scale, allowing us to unravel complicated quantum matter and reveal elusive microscopic quantum properties. Our research focuses a broad spectrum of correlated and topological states of matter, providing a unique opportunity to observe exotic quantum phenomena and contributing to the development of quantum technologies. Our laboratory is a member of IBS Center for Van der Waals Quantum Solids and focuses on research into two-dimensional van der Waals material devices with advanced scanning probe microscopy, leading to the discovery of new quantum phenomena and their translation into future information technology.
