Electronic dynamics in nanomaterial: Electron Transfer between quantum dots and metal oxides

Abstract

This project aims to train the student in practical and theoretical aspects of linear and nonlinear optical phenomena, and the study of photo-excited carrier´s ultrafast dynamics in lead-sulfide nanomaterials. Using an ultrashort laser system (< 100 fs), the candidate will investigate the ultrafast electronic dynamics in nanostructured materials by the light matter interaction. To this end, it will be necessary to set up a pump and probe experiment with temporal resolution better than 100 fs and operating in the near infra-red. This experiment will be used to investigate electron transfer between PbS quantum dots and layers of metal-oxide. This study is important not only for the understanding of fundamental science but also for applied science, specifically, for the development of third generation solar cells.
