Congratulations to Dr. Miriam Bohlmann Kunz for successfully defending her Ph.D. thesis entitled, “Ultrafast Pulse-Shaping Applied to Multi-Dimensional Spectroscopy and Novel Microscopy Methods” on August 26, 2022!
Semiconducting thin films are the building blocks of next generation photovoltaic devices. In many of these devices, energy transfer is necessary for creating a photocurrent from the initially excited electrons. Studying the energy transfer is a difficult task as it happens on the femtosecond to picosecond time scales and between grains that are 10 nanometers to 1 micrometer in diameter and layers that are hundreds of nanometers thick. The tools with both adequate spatial resolution and time resolution to resolve the energy transfer are limited. In this dissertation I will describe the use and development of methods to study the energy transfer within semiconducting thin films.
