Welcome to the Shim Research Group!
The overarching goals of our research program are 1) understanding charge separation, recombination and injection/extraction processes in nanoscale materials and 2) developing heterostructures of such materials where size and shape (in addition to composition) dependent properties can be exploited to manipulate charge carriers with nanoscale precision. Efforts range from new materials design and synthesis to structural and optical characterization, assembly/organization/fabrication and device physics and engineering. The results from these efforts empower the development of next-generation technologies, especially in solar energy conversion and energy-efficient lighting/displays.
Members of the Shim research group utilize a variety of different methods/techniques including chemical syntheses, TEM, SEM, AFM, XRD, XPS, electron transport measurements, optical and Raman spectroscopy, and micro/nanofabrication in carrying out their research. There are several on-going collaborations with research groups within and outside the Department of Materials Science and Engineering as well as in other institutions.
