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.
