We study the physical and chemical properties of nanostructured thin films and devices. Based on our fundamental findings, we develop the next generation of high-performance optoelectronic and photonic devices, including solar cells, LEDs, lasers, photodetectors, transistors, and chemical sensors. We work with a wide variety of nanomaterials, from colloidal quantum dots to molecular organics to hybrid organic-inorganic materials. With our lab's expertise in thin-film deposition and unique vacuum transfer system, we design and prototype new thin-film structures, devices, and systems.
