Top-emitting organic light emitting diodes (Top-OLED) were made with Al capped with very thin platinum (Pt) and praseodymium oxide (Pr/sub 2/O/sub 3/) as the anode. Efficient Top-OLED were obtained ...

In this paper, we investigate sputtered physical vapor deposition (PVD) AlN nucleation layer effects on crystal quality and efficiency of GaN-based light-emitting diodes (LEDs) prepared on high-aspect ...
