Abstract

In this paper, we have demonstrated that P-type dehydrated nanotube titanic acid (DNTA) can significantly enhance hole injection and transport in holes-only transport devices. In the low field region, the dominant conduction mechanism is injection limited. This gradually transitions to space charge limited current via trapped charge limited current with increasing applied voltages. Through fabricated and characterized organic light-emitting diodes (OLEDs) and by using a DNTA-poly(vinylcarbazole) (PVK) nanocomposite as the hole transport layer, we found that the performance of these devices was greatly improved with a higher luminance, an enhanced efficiency, and a lower turn-on voltage.
