| Research Abstract |
Dependence on carrier concentration of carrier mobility and contact resistance of carrier injection from a metal electrode were measured for organic semiconductor single crystals. The carrier concentration was controlled by an electric double-layer transistor (EDLT)structure employing an ionic liquid as an electrolyte. The contact resistance from a gold electrode to the organic semiconductor firstly decreased by increasing the carrier concentration, and then increased by increasing the carrier concentration. The carrier concentration dependence of the contact resistance is inversely proportional to that of carrier mobility. This behavior is well explained by the diffusion-limited thermionic emission model.
