Single crystal organic field effect transistors (FET) fabricated by adhering thin crystals of tetracene to silica substrates were investigated. The intrinsic transport properties of tetracene single crystals were measured. It was found that these FETs exhibit mobilities as high as 0.1 cm 2V -1s -1 and I on/I off ratios in excess of 10 9. It was also found that the larger devices show thermally activated mobilities.
