Defect Control in Semiconductors

The ability to control and manipulate defects in semiconductors has revolutionized the electronic and optoelectronic industries that make up modern society. In the case of silicon semiconductors, p– and n-type doping has enabled the proliferation of solar photovoltaics – a critical technology to combatting climate change. While for quantum technologies, nitrogen-vacancy (NV) defects in diamond can be coherently controlled and used as quantum sensors to improve energy efficiency in batteries. Although there has been great success in controlling defects in classic semiconductors, such as silicon, future disruptive technologies will require the ability to isolate and utilize defects in more complex material systems and in ways that have never been achieved. Therefore, my research has focused on new techniques to synthesize, characterize, and control defects in advanced materials, for example metal halide perovskites and quantum-grade diamond, that are critical to solar energy harvesting, efficient light emission, and quantum information systems. Specifically, I enjoy using chemistry to create materials with desirable properties and utilize advanced spectroscopic tools to further understand, inform, and improve materials processing. My work is deeply motivated by climate change and in developing a new generation of quantum sensors for energy applications and for brain mapping.
