Vanadium oxide (V<inf>2</inf>O<inf>5</inf>) and 4,4',4''-tris(N-3-methylphenyl-N-phenyl-amino)-triphen ylamine (m-MTDATA) doped V<inf>2</inf>O<inf>5</inf> film, respectively, is used as a buffer layer between source/drain electrodes and organic active layer in organic thin film transistors (OTFTs) to improve the electrical characteristics. Results show that(More)
An anodic aluminum oxide (AAO) template was formed by a two-step anodization process. Carbon nanotubes (CNTs) were successfully synthesized along with AAO pores and the diameters of CNTs equaled those of AAO pores. The lengths of CNTs during a chemical vapor deposition synthesized process on the AAO template were effectively controlled. These AAO-CNTs(More)
In recent years, the developments in the OLEDs have gradually reached very advantageous of existence. These advantageous characteristics include self-luminous, wide viewing angle and low power consumption, etc. which make OLEDs very useful for numerous display applications and lighting devices. To effectively improve the characteristics of an OLEDs, there(More)
