DNA Interlayers Enhance Charge Injection in Organic Field-Effect Transistors

摘要

Charge injection barriers can often be found at electrode-organic semiconductor interfaces. These interfaces play a key role in determining device characteristics and performance.For example, in polymer light-emitting diodes (PLEDs), these barriers can cause imbalanced electron and hole densities and therefore lower the device efficiency. Modification of the active layer/cathode interfaces can also lead to enhancement of the power conversion efficiencies in polymer solar cells.
