Our research covers a variety of fundamental and applied topics on materials and devices for future electronics. Our interest in this topic is motivated by the potential of organic (plastic) electronics to greatly impact the future semiconductor industry by low-cost, high diversity and low power consumption. Examples of plastic electronics applications include: OLED (organic light emitting diode) TVs, flexible plastic solar cells, flexible displays, wearable (textile) electronics, chemical and biological sensors.
The simplest unit in many of the plastic electronic applications is the organic field-effect transistor (OFET). Our efforts aim to improve the performance of OFETs by better understanding and control of charge injection and transport, charge trapping and de-trapping, defect generation, migration and lifetime. We will investigate crystal structure and electronic properties of a variety of organic semiconductors as the active materials in OFETs. One critical issue in organic electronics is that the device performance is dominated by the micro- and nano-scale structure features of the organic film, which in turn is dictated by the chemical structure and processing. The structure, processing and performance are thus strongly influenced by each other. Our studies will focus on describing the structure-processing-property relationship that governs the physical processes in organic semiconductors. The results will be providing the frame for comparisons between novel organic semiconducting molecules and will promote the discovery of materials with enhanced electronic properties. Considerable effort will be concentrated towards investigation of novel materials, which complement the incorporation in OFETs with additional functionality such as ferroelectricity and magnetism. The third line of interest is Organic spintronics, which will be performed in collaboration with National Institute of Standards and Technology.
The program consists of exciting and interdisciplinary topics of research, providing opportunities for both undergraduate and graduate involvement.
