Congratulations to Dr. Zach Armstrong for successfully defending his Ph.D. thesis entitled, “Ultrafast Two-Dimensional White-Light Spectroscopy of Excitons in Disordered Environments” October 7, 2022!

Excitons in semiconductors often experience disordered environments. Disorder can impact the energetics and relaxation dynamics on ultrafast timescales, both having implications for the operation of photovoltaics. In this dissertation, I study the impact of disorder on novel semiconductors using two-dimensional white-light (2DWL) spectroscopy and microscopy.

Dr. Armstrong will spend a season working as ski patrol before he begins a postdoctoral position at the University of Colorado.

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.
