Electronic Structure and Topology in 2D Multiferroic Quantum Materials
Abstract
The proposed research aims to discover and understand two-dimensional (2D) multiferroics from experimentally known van der Waals (vdW) crystals, a class of materials formed by weakly bonded ultra-thin 2D layers that exhibit ferroelectric, ferroelastic, and-or ferromagnetic properties. Such multiferroics hold significant scientific and technological promise, including applications in transducers, actuators, photovoltaics, and nonvolatile memories. However, their development faces challenges such as stringent symmetry requirements and thermodynamic instability. Despite progress in thin-film and interfacial multiferroics, room-temperature magnetoelectric multiferroics with strong coupling remain elusive. The project focuses on discovering 2D ferroics and multiferroics from experimentally known crystalline compounds, investigating their coupling with various physical degrees of freedom such as orbital, spin, and valley, and controlling electronic topology through vdW heterostructure engineering.
