Peng and fellow researchers in physics science and technology department at Lanzhou University in China, develop numerical models for the current conduction in single-layer devices, including both injection and bulk effect for both trap-free organics and organics with traps exponentially distributed in energy. They also investigate the dependence of the current density on the operation voltage, the thickness of the organic layer, and the trap properties, finding that the current density decreases nearly exponentially with the thickness of the organic layer and the relative trap depth (l), and is inversely proportional to the l-th power of the total trap density. The research could lead to improvements in organic light-emitting diodes, which are beginning to enter the market in the form of flat-panel displays.

Investigates mechanism of charge carrier transport in organic semiconductor thin film devices (OTFDs). This book develops numerical models for the conduction in single layer OTFDs including both injection and bulk effect for both trap free organics as well as organics with traps exponentially distributed in energy.
