Our research concerns the study of the optical and electrical properties of thin film materials and devices. Films range from molecular to inorganic to nanostructured and quantized materials, while devices are often those such as photovoltaic (solar) cells, photodetectors, transistors and light emitting devices (LEDs). Our studies rely on deriving a comprehensive understanding of the optical, electronic, and structural properties of the materials and heterogeneous interfaces established within devices to enable future device performance and functionality improvements.
