In this work, vertically aligned metal oxide nanorods(ZnO, $TiO_2$, $WO_3$) were grown onto CuO film at the room temperature. The fabricated nanorods of 90nm~500nm diameter range and $1{\mu}m{\sim}15{\mu}m$ of length range. Growth of metal oxide nanorods only depends on thickness of CuO film in this method, and it is grown at both of room temperature and high temperature. That means, it is much faster mathod to make the vertical metal oxide nanorods than old method such as hydrothermal method.

We have developed new electrical dopants of rhenium oxide ($ReO_3$) and cupper iodide (CuI) as p-dopants and rubidium carbonate ($Rb_2CO_3$) as an n-dopant, respectively. $ReO_3$ has advantage of low temperature evaporation (about $300^{\circ}C$) with enhanced device stability. Various kinds of high performance organic light emitting diodes have been realized, including bottom emission, tandem, and top-emission OLEDs.
