Research Abstract

Correlation of charge carrier dynamics on the nanosecond to millisecond time scales with film morphology and chemical structure of organic semiconductors has been investigated by the combination of quantum beam(mainly, light pulse and high-energy electron beam) and microwave. Improvement of the measurement system and development of new analysis method allowed for versatile evaluation such as electrode-less anisotropic mobility with high angle resolution, separation of hole electron contributions, and mobility determination based only on experiments. Through this research, fundamental aspect of charge carrier dynamics was established towards the realization of high-performance organic electronic devices.
