Research:
Our research interests are in the area of organic optical, electric, magnetic materials, smart materials and nanoelectrode arrays.
Research on optical materials focuses on developing 2nd order nonlinear optical (NLO) polymers that have many important applications including electro-optical modulation and terahertz generation etc. Our efforts focus on design and synthesizing NLO polymers that have large nonlinearity while low optical loss at the fundamental wavelength.
Organic semiconducting and conducting polymer is another focus of our research. Organic semiconducting polymers are promising materials for flexible, low-cost, and large area electronics such as light emitting diode, field effect transistor, and solar cell. Currently we are working on semiconducting polymers that self-assemble into novel architectures that can lead to high charge mobility, multi-channel electron transport, and novel processiblity.
Inspired by recent progress of diluted magnetic semiconductor (DMS) that is required to fabricate spintronics (next generation of electronics?), we are exploring various mechanism that may lead to novel organic-inorganic hybrid magnetic semiconductors.
Smart materials are defines as materials that reversibly or permanently change certain properties under external stimulations such as light irradiation, electric field, magnetic field, temperature change, etc. We are currently working on photo-responsive materials that change conductivity, magnetism, and shape under irradiations.
Nanoelectrode arrays (NEAs) offer many advantages over conventional electrodes including high signal/noise ratio, fast response and decreased deleterious effects of solution resistance etc. We are developing fabrication methods that lead to robust NEAs with novel electrochemical properties.
Graduate Students and Postdoctors:
Graduate students in Liao's Lab will be trained in a highly interdisciplinary area of organic synthesis, polymer chemistry, material science, nanoscience and device engineering. They will do research in exciting and frontier areas in materials chemistry. Students who are willing to face significant while challenging scientific problems are welcome to Liao's lab.
