Dr. Yaguo Wang: Renewable Energy and Atomic Simulations of Energy-Conversion Materials

Dr. Wang’s research covers a broad spectrum of topics in renewable energy, including ultrafast optical spectroscopy, nano/micro-scale heat transfer, thermoelectrics for waste heat recovery and microchip cooling, photovoltaics, etc. She is also interested in atomic simulations of energy-conversion materials and thermal management in nanoelectronics. Her group will set up ultrafast time-resolved phonon spectrometer and THz frequency spectrometer at The University of Texas at Austin, which are capable of capturing the ultrafast phenomenon occurring from femtosecond (10-15 s) to picosecond (10-12 s) time scale.

Currently Dr. Wang’s research interests include:

Ultrafast optical spectroscopy to detect and control phonon/electron dynamics in thermoelectrics, photovoltaics and interfacial systems for applications in waste-heat recovery, solar cells and batteries

Theoretical and computational studies of atomic-level carrier transport with lattice dynamics and molecular dynamics simulations

Thermal-physical property characterization in nano-device

Ultrafast phonon spectroscopy has been applied to study the phonon transport in Bi2Te3/Sb2Te3 superlattice, a promising TE materials for solid-state cooling.
