Our research includes work on carbon-based organic electronic and semiconducting devices including organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and organic field-effect transistors (OFETs). We are also studying and developing several types of devices based on inorganic semiconductor materials including quantum dots for infrared (IR) sensing, heterojunction metal oxides for ultraviolet (UV) photo-detectors, hybrid organic lead halide perovskites for high efficiency solar cells as well as high-gain permeable vertical transistors. Our research focuses on revealing physical properties of novel electronic/semiconducting materials with advanced characterization methods, designing new device architectures, and developing new processing methods for high performance optoelectronic devices.
