Perylene: A promising organic field-effect transistor material

Field-effect transistors based on single crystalline perylene have been pre pared and analyzed in the temperature range from 50 to 300 K. Room temperat ure electron mobilities as high as 5.5 cm(2)/V s have been achieved. In add ition, ambipolar device operation, i.e., n- and p-channel activity, is obse rved. The temperature dependence of the electron and hole mobilities is dis cussed in the limits of hopping and band-like transport mechanisms. (C) 200 0 American Institute of Physics.
