ZnO Based Short Wavelength Laser

Cermet, in collaboration with the Palo Alto Research Center, will fabricate and test a ZnO based semiconductor laser diode. Using Cermet's in house grown ZnO single crystal wafers, homoepitaxial films and epiwafers will be grown and characterized. Alaser diode will be designed with a prototype fabricated at the end of Phase II. The applications for a room temperature, ZnO p-n junctions, LEDs and laser diodes are vast. A transparent p-type conductor would be available to increase the efficiency ofestablished emitter and detector applications, including light emitting diodes, laser diodes, sensors / photodetectors, and photovoltaics. Additionally, a new family of transparent ZnO-based devices could be developed, including efficient UV/blue lightemitting diodes, sensors / photodetectors, and laser diodes.
