Film Integration Steps Closer to Flat Panel Application

Facebook X LinkedIn Email
Three-color integration of rare-earth-doped GaN thin films may now be possible for use in flat panel displays. Using a combination of shadow-masking and photoresist-liftoff techniques, Don Lee and Andrew Steckl, researchers at the University of Cincinnati, have laterally combined green-emitting GaN:Er and red-emitting GaN:Eu films on the same substrate. The films were electronically stimulated through circular Schottky electrodes fabricated by indium-tin oxide sputtering. The figure above shows the two films during the shadow-mask phase of production. The researchers expect that the...Read full article
