 Title: Conducting Nanocrystal Solids for Optoelectronic Devices Authors: Shukla, Harnik Advisor: Sargent, Edward H. Department: Electrical and Computer Engineering Issue Date: 30-Jul-2008 Abstract: Nanocrystal solids represent an exciting new class of materials. These are often referred to as artificial solids, in which the nanocrystals take the place of atoms in traditional solids. This thesis reports the utility of field-effect transistor measurements to elucidate charge transport parameters, such as charge carrier density and charge carrier mobility in a nanocrystal solid. The evolution of these parameters with chemical treatments is followed and correlated to improved performance in photovoltaic devices. Chemical treatments are demonstrated to simultaneously engineer interparticle spacing, doping and electronic coupling in nanocrystal solids. The nanocrystal solids are then utilized as building blocks for fabricating all nanocrystal heterostructure. A type-I nanocrystal heterostructure is fabricated to demonstrate efficient electroluminescent device in the infrared communications wavelength. The device emits at peak wavelength of 1.58 um with an effciency of 0.5%. URI: http://hdl.handle.net/1807/11165 Appears in Collections: MasterThe Edward S.
