Abstract

The surface of ITO in OLEDs was treated with $HfO_x$ deposition process using an atomic layer chemical vapor deposition system. The treatment at room temperature for 5 cycles exhibited significantly improved electroluminescent characteristics compared to the OLEDs without any treatment, which is believed to be caused by the increased holes injection efficiency.
