Nanoelectronics and Energy Conversion Lab @ NJIT
Research in the Nanoelectronics and Energy Conversion Lab focuses on the discovery of new nanomaterials, the design of novel high-performance device architectures, and the experimental demonstration of device prototypes. Our particular interest is in colloidal quantum dot-based devices, in which semiconductor nanocrystals with tailored electronic properties are used as fundamental building blocks to construct devices from the bottom-up. This approach provides an opportunity to exploit unique properties arising from nanoscale components and to explore unconventional device concepts and designs. One of our recent efforts includes the development of paper-based thermoelectric devices that offer a compelling combination of low-cost, high-throughput fabrication and flexible form. These devices can produce electrical power from body heat (curved surfaces) with applications ranging from wearable/portable electronics to "deploy-and-forget" wireless sensor networks. Other projects include quantum dot-based sensors and imagers that concentrate on developing new infrared sensing nanomaterials and device structures for high sensitivity/high temperature photodetection.
