| Research Abstract |
This project has aimed at elucidating fundamental electronic states at the novel interfaces of organic single crystal semiconductors. Some of printed organic crystalline semiconductors show remarkably high mobility as compared with that of amorphous silicon, so that these materials are expected to be implemented in next-generation printed and flexible electronics industry. After our comprehensive studies of such systems from chemical, physical and engineering approaches, we got results of even higher mobility in newly synthesized semiconductors. The charge transport mechanism is continuously studied in terms of fundamental electronic natures between hopping and band-like transport. Furthermore, we have introduced experiments of the two -dimensional organic single-crystalline interfaces under high pressure, so that the structure-property relationship exhibited anomalous and giant pressure effects in thiphene-based organic single-crystal transistors. The above results gives significant contribution in understanding electronic properties of organic two-dimensional electronic systems.
