Polaron Dynamics in Organic Molecular Stacks

Organic semiconductors have emerged as ideal candidates for the design of optoelectronic devices such as photovoltaics 1 and light-emitting 2 diodes due to present important traits which are required for the development of new green energy solutions. The potential advantages in terms of low cost, flexibility, and low environmental impact make these materials attractive for the electronics industry. In order to increase the device performance, a better understanding at a molecular and even at the atomic scale of the charge transport properties is absolutely required 3,4 . Particularly, the polaron stability and dynamics are of critical importance for the device performance.
