Abstract

In this presentation I will share some experiences, successes and struggles, of teaching at a liberal arts college and staying active in a research field. In the second half of the presentation I will present the results of research involving a spectroscopic study of Co:ZnO. ZnO has attracted interest as transparent conducting window for solar energy conversion and doping is a means to extend its useful spectral range. Despite decades of investigation of Co:ZnO by optical spectroscopy and photoconductivity, the precise nature of the 4 A2→4 T1 manifold excitation that gave rise to conductivity was little understood. Variable-temperature photoconductivity measurements reveal a thermally assisted ionization process that enhances the d-d photoconductivity at higher temperatures as well as an additional temperature independent pathway.
