Microscopic Theory of Optical Excitations in Interface-Dominated Material Systems (B04)

• Subject Area: Theoretical Condensed Matter Physics
• Term: from 2013 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 223848855

This project deals with the microscopic modelling of electron-hole-pair excitations in interface dominated semiconductor materials. The goals are the analysis of the optically linear and nonlinear response and the formation dynamics of spatially inhomogeneous excitons where the constituting electrons and holes are located in neighbouring material regions that are separated by an internal interface. As model systems, we focus (i) on semiconductor heterostructures and (ii) van-der-Waals bonded systems consisting of quasi-two-dimensional layers of transition-metal dichalcogenides.
