Electromechanics of Excitons in 2D Materials

Quantum emitters based on excitons in 2D materials and their heterostructures have great potential for quantum photonics applications. Methods of electrical and mechanical controlling excitons and their quantum emission are highly desirable. This talk will discuss electromechanical methods, including acoustic waves and strain engineering, to control, transport, and modulate excitons and quantum emitters. We show that, in 2D systems, excitons can be transported by acoustic waves beyond the diffusion limit to induce non-local effects, and the internal phonon states are heralded by single-photon emissions from strain-engineered 2D quantum emitters.<br/>Biography - Mo Li<br/>Dr. Mo Li is a Professor in the UW Department of Electrical & Computer Engineering and the UW Physics Department.
