Abstract

We will investigate optical and magnetic properties of emerging twisted van der Waals heterostructures. In order to meet this goal, the project will have the following specific objectives: (1) Implement strategies to achieve high-quality samples of twisted 2D heterostructures; (2) Study the effects of moiré pattern on the physical properties of interlayer excitons (2) Study of magnetic and optical properties of these heterostructures with different twisted angles; (3) Study magnetic proximity effects on twisted heterostructures based on 2D magnets.
