Project B1

Interaction of Exciton, Carrier and Dangling Bond Spins in Colloidal Nanostructures

In this project, we will study optical spin orientation and spin dephasing with ultrafast magneto-optical techniques. These concepts will be applied to a broad range of materials, ranging from epitaxial semiconductors to novel nanocrystals. The overarching aspect is the investigation of structures which exhibit much longer carrier lifetimes when compared to most direct-gap bulk materials and nanostructures. To this end, we will investigate material systems featuring indirect transitions. Important examples comprise group IV bulk materials and heterostructures as well as (In,Al)As/AlAs and CdSe/CdS quantum dots.
