| Research Abstract |
In order to realize organic electro-optical devices with high speed operation, electro-optical devices have been fabricated by solution process with simple fabrication technique. The fabricated devices have been operated with similar characteristics with those fabricated by vacuum process. Both the light emitting anddetection devices can be operated above 80 MHz. Insertion of self-assembled monolayerbetween electrode and organic layer improves carrier injection and control the carrier trap formation, and results in high speed operation. The devices parameters are analyzed by impedance spectroscopy.
