Development of a Novel Optical Spectroscopy Tool for Studies of Coulomb Correlations in Semiconductors

Abstract

In this project, we have further developed two-dimensional Fourier transform spectroscopy as a powerful tool to study many-body physics in semiconductor nanostructures. In particular, we investigated the interplay between disorder and Coulomb correlation in semiconductor quantum wells. Monolayer fluctuations in thickness of a semiconductor quantum well lead to the formation of different types of excitons clearly resolvable in the optical spectrum. Whether or not these excitons are coherently coupled via Coulomb interaction is a long-standing debate.
