Nanotechnology Initiative Revision of Quantum Engineering of Nanostructures for Optoelectronic Devices with Optimum Performance.

摘要

The investigators have undertaken several efforts underlying the enhancement of the performance of nanostructure-based quantum-dot-based optoelectronic devices. These include: the use of colloidal quantum dots as optoelectronic elements; investigating novel nanostructures (including graphene and CNTs as contacts) as components of quantum-dot based optoelectronic devices; investigating confined phonon effects in novel components of the integrated nanostructure-based optoelectronic structures; investigating energy transfer between quantum dot and PS-I; and the investigation of photodetector structures from these nanostructures and conducting polymers. Specific achievements include: first measurement of FRET times between PS-I and semiconductor quantum dots; measurement of large NDR in organic-inorganic optoelectronic structures; measurement of confined phonons in quantum dots; and design of novel three- color organic-inorganic photodetectors.
