| Research Abstract |
We revealed that organic semiconductor rubrene single crystals grown from vapor phase have molecularly flat surface in wide region by using a laser confocal microscope with a differential interference contrast microscope for the first time. The observations of the crystal growth, which is shown the transition of molecular steps on the surface, were contributed to a clarification of growth mechanism. These single crystals have been shown high FET characteristics.
