Thermoelectric Energy Conversion
Thermoelectrics (TE) offers a green option for renewable energy conversion and waste heat harvesting. ZT group aims to improve the energy conversion efficiency by enhancing the firgure of merit of TE materials and devices. At the material level, we investigate TE materials beyond the traditional ones, including oxide and organic materials. At the device level, we develop comprehensive device modeling and evaluate the performance of novel device design.
Micro/NanoElectronics Cooling
As the electronics industry expands rapidly and chip fabrication technology evolves towards further miniaturization, power density and heat flux increase steeply. ZT group targets at developing energy-efficient cooling technologies to improve the device performance and reliability. Of particular interest are to revolutionize thermal interface materials and to mitigate hotspot temperature by rigorous device modeling.
Thermal and Electrical Properties of Polymers
Understanding thermal and electrical properties of polymers is challenging because of the complexity of their structures. We have uncovered effects of polymer chain confinement, topology and morphology on thermal conductivity, and thermoelectric properties of conducting polymers. We are identifying the crucial parameters underpinning the transport properties for a diverse array of applications ranging from thermal insulation, 3D printing, flexible electronics, to biosensors and drug delivery.
Functional Thermal Materials/Devices
To achieve thermal rectification or switching functionality in single material is appealing yet challenging as it requires a drastic change in thermal conductivity when heat flow direction or external condition changes. We focus on advancing the fundamental understanding of unique thermal transport properties of asymmetric, anisotropic, and responsive polymers to enable functional thermal devices for thermal management and phononic information technology.
