Abstract
The electrical and optical characteristics of MEH-PPV (Poly [2-methoxy-5-(2’-ethyl-hexoxy)-1, 4 phenylenevinylene]) as active layer has been investigated in the organic light emitting diode (OLED).The proposed structure is a monolayer device; consisting MEH-PPV sandwiched between high work function anode (ITO) and a relatively low work function cathode (Ca).The proposed structure was simulated by device simulation software ATLAS from Silvaco Inc. Simulation includes various organic models like Poole-Frenkel mobility model and Langevin Recombination model; these models are enabled in Atlas Silvaco. In order to optimize OLED performance, we propose to change some device parameters like doping concentration and thickness. Also, we have investigated the effect of high and low work function metal as cathode and anode respectively on the device performance.
