Abstract

Recent advances on the development of new methods for synthesis of semiconductor nanostructures has allowed for better control of their optical and electronic properties. In those structures, quantum confinement changes the electronic structure changing existing and generating novel physical phenomena which are of interest not only for fundamental science but also for technological applications. This is the case of the enhanced multi-exciton generation rate in semiconductor quantum dots, which can be useful for application in generation-III solar panels. In this project, we propose to use ultrafast and nonlinear spectroscopy to study the dynamics of photoexcited carriers and the nonlinear optical response in nanostructured semiconductors. In particular, we will investigate multi-excitons interaction and multi-photon absorption in visible and near-infrared emitting nanoparticles which are candidates for applications on solar cells, 3D microscopy and telecommunications. Finally, this project will contribute to the expansion of ultrafast and nonlinear spectroscopy studies not only at UNICAMP but also, in the entire São Paulo State. (AU)
