A range of microelectronic devices, including electroluminescent (EL) devices, OLEDs, LEDs, photovoltaics, chemical sensors, and lasers among others, would benefit immediately from a viable p-type transparent conductive oxide.  None are routinely available, although there exists limited evidence that they could be made.  This project will optimize an existing low-cost,  scalable MOCVD (metal oxide chemical vapor deposition) technology to produce p-type transparent conductive oxides of good and repeatable quality, which ultimately would be made  routinely available to device producers.  In Phase I, MOCVD techniques were applied to produce p-type transparent and conductive oxides.  The p-type material was achieved with relatively high conductivity on low-cost substrates.  Phase II will further optimize the process for the production of p-type transparent conductive oxides.  The applicability of the process to enable new products, specifically blue/UV LEDs, will be demonstrated.

Commercial Applications and Other Benefits as described by awardee:  New p-type transparent/conductive oxides should enable improved OLED devices; alternative/enhanced EL devices; new photovoltaic devices (solar cells and/or photon detectors); oxide junction based chemical sensors; transparent transistors; and UV LEDs and lasers.
