Effects of optical and environmental parameters on angle-resolved photoemission from materials
Abstract/Contents
- Abstract
- Studies in condensed matter physics have led to the discovery of a profusion of materials with interesting quantum properties, such as superconductors and topological insulators. The wide variety of material systems demands a wide variety of experimental techniques. I focus on two techniques: angle-resolved photoemission spectroscopy (ARPES), which measures electronic band structure in the energy and momentum domains; and time-resolved ARPES, which probes out-of-equilibrium phenomena by extending ARPES to the time domain. There are many parameters which can affect measurements of quantum materials. I show how varying nonlinear crystal thickness in an ultrafast laser setup allows for fine-tunable time and energy resolution in time-resolved photoemission. Achieving a high degree of control over resolutions is critical for enabling new experiments. I also investigate how Bi2Se3 surfaces change to bismuth upon exposure to air, potentially affecting results of surface-sensitive measurements in atmosphere. High control and understanding of temporal, spectroscopic, and sample composition properties, as well as the optical and environmental parameters which control them, are essential to performing successful experiments on quantum materials.
