| Research Abstract |
Device structures utilizing charge carrier doping with molecular dopants were newly proposed for improving and controlling device performance of organic field-effect transistors (OFETs), and those availabilities were confirmed by both device simulations and experiments. In addition, toward establishing device scaling rules, a new methodology for extracting gate-voltage-dependent contact resistance and channel parameters (e.g., field-effect mobility) from the electrical characteristics of a single OFET device was developed as well as a new device simulation technique considering carrier injection barriers (Schottky barriers) for realistic OFET devices.
