Welcome to the Advanced ThermoEngineering Laboratory

Our group tries to expand the limits of thermal transport—e.g. heat transfer through conduction or
hermal conductivity—mainly in solids with nanostructure as shown in the figure below.
This could have great effect on daily life of people based on heat energy and thermal properties.
Just like the invention of the transistor, it demonstrated external tuning of electrical conductivity and
laid the foundation of information processing and the digital age.
For means of application, we invest our efforts into improving energy conversion efficiency
of the thermoelectric (TE) device, which can directly convert heat into electricity (power generation)
and vice versa (refrigeration) by manipulating thermal and electrical transport properties of the TE materials.
We also work on thermal modeling for heat dissipation and/or isolation in electronics to cool them down and
in passenger vehicles to provide comfortable cooling.

Feel free to go through our recently updated publications to see
how we have been active in our endeavor in contributing to the society on energy.

This can be accomplished with nanostructured materials,
where in phonon wavelengths and their mean free paths can be tuned.
