Welcome to hengwang group
We are a group of experimental material scientists at Illinois Institute of Technology, right next to the heart of the vibrant city of Chicago. We study the transport of charge (aka, electrons or holes) and heat (aka, phonons) in semiconductors, with a focus on thermoelectric effects
Understanding, and being able to manipulate how the electrons and phonons move through a solid form the foundation of semiconductor industry and essentially every piece of electronic devices. The same question is of great importance to numerous areas of material research: thermoelectrics, photovoltaics (solar cells), battery, flexible electronics, just to name a few.
Now that you are here, please spend some time to learn more about our research, our team, or just have fun. If you are interested to learn more about the design and characteristic of thermoelectric devices for cooling, check out our TEC designer site (still under construction): https://1075305759.wixsite.com/tecdesigner
Oh, We would also like you to know that we are looking for motivated undergraduate and Masters students to join the group. please email us.

Happy Birthday Thermoelectricity
Exactly 200 years ago, on August 16, 1821, Thomas Johann Seebeck reported to the Royal Academy of Sciences in Berlin about his discovery of thermoelectricity. Actually, Seebeck was not the first to observe a thermoelectric effect (and of course he didn't interpret it correctly), which was described about fifty years before by Alessandro Volta. But nonetheless, the thermoelectric community decided to celebrate this date as the birth of thermoelectricity.
Happy Bicentennial Anniversary, Thermoelectricity!

Our New Lab Space
We have moved to lab 013-015, which is a much bigger space than our old lab! Most things worked out nicely so it has been a happy move, even though no one likes moving.
