NICOP - Solution-Processed Metal Oxide Thin Films for Quantum Dot-Based Optoelectronics
Abstract
This proposal seeks to develop novel titanium-based organometallic precursors thatdecompose readily into a conductive (>1k ??/???) and transparent (>90% transmission in theVis/NIR region) metal oxide thin film under the influence of ultraviolet (UV C region - 254nm) radiation. These transparent conducting oxides (TCOs) will be optimized for filmuniformity, characterized structurally/spectroscopically, and ultimately embedded within aquantum dot-based optoelectronic device. Innovation from this project is derived from theprocess development. Current production of titanium-based TCOs requires high annealingtemperatures (450 ??C) to achieve acceptable transmission and conductivity values. Theresearch proposed within this document seeks to eliminate this high-temperature process,which would allow for the fabrication of solution-processed optoelectronic devices that arehighly sensitive to elevated temperatures. Currently, there is a need across all DoD to developoptoelectronic systems (e.g., imagers, detectors, etc.) that operate hyperspectrally (i.e., candetect wavelengths across a large portion of the electromagnetic spectrum) due to thedynamic environment in which said devices operate within. This project has relevance withinseveral Naval S&T Focus Areas such as the Platform Design and Survivability thrust (i.e.,materials), the Power & Energy thrust (i.e., renewable energy), the InformationDominance/Cyber thrust (i.e., communications/information technology), and theExpeditionary and Irregular Warfare thrust (i.e., situational awareness). Collaborators forthis project include Dr. Diogenes (Dio) Placencia from the US Naval Research Laboratory(Electronics S&T Division ??? Optoelectronics & Radiation Effects Branch ??? NanoOptoelectronics Section - Code 6814), an expert in nanomaterial interfaces and devicefabrication. In addition, Dr. Paul Armistead (ONR ??? Code 33) has pledged interest andfinancial support for the project. Desired outcomes for this project is at the very least acomprehensive publication that includes all the efforts detailed above, in addition toconference presentations, and an international workshop through the CSP funding vehicle.
