Nanoelectronics

We are an interdisciplinary research group that studies nanoelectronic devices made from colloidal semiconductor quantum dots (QDs). Colloidal QDs are nanometer-sized single crystals of semiconductor suspended in a solution that offer exciting opportunities for scientists and engineers to develop ultracheap, pervasive devices for emerging ubiquitous electronics and ambient intelligence era. Our research effort is concentrated in two fronts:

QD Infrared Photodetectors with Low SWaP-C (size, weight, power consumption, and cost)

Photodetectors operating in the atmospheric transmission window of 8-12 μm (long-wavelength infrared) are of great importance for civilian and military applications.

Ambient Energy Harvesting Using Thermoelectric QDs

Breakthroughs in energy harvesting hold promise for “deploy-and-forget” wireless sensor networks and other distributed or portable power applications.
