Mid-Wave Infrared Photodetectors
Using a modified PV device architecture, we report up to 2 orders of magnitude improvement in the sensitivity of the HgTe CQD photodetectors
Slow Auger Relaxation in HgTe CQDs
The biexciton lifetimes in HgTe colloidal quantum dots are measured as a function of particle size.
Synthesis of HgTe CQDs
Nonaggregating HgTe colloidal quantum dots are synthesized without thiols as stabilizing ligands. The dots are spherical with a size tunability from 4.8 to 11.5 nm.
Electrochemistry of Colloidal Quantum Dot Films
The absolute positions of the energy levels of colloidal quantum dots of Hg(S, Se, Te), which are of interest as mid-infrared materials, are determined by electrochemistry.
Congratulations to John, who won Best Poster at the ACS conference!

Ananth receives the Windt Graduate Student Travel Award 2022! He will be presenting his work at the MRS Spring 2022 Conference
Welcome to Xingyu Shen, who joins the group as a first year student!
Chris’s review article on many-body dynamics is published in Chemical Reviews!
Matt receives the William E. Spicer – Thomas N. Casselman Award
Congratulations to Matt for his award for best student paper at the U.S. Workshop on the Physics and Chemistry of II-VI Materials (a.k.a. the II-VI workshop)!
Xin and Matt’s paper highlighted as a “breakthrough for infrared camera technology”
Xin and Matt devised a detector using quantum dots tuned to detect different parts of the infrared spectrum, allowing dual-band infrared imaging. You can read more about it in this UChicago News article, and the technical paper was published in Nature Photonics.
