PRECURSOR ROUTE PENTACENE METAL-INSULATOR-SEMICONDUCTOR FIELD-EFFECT TRANSISTORS

Metal-insulator-semiconductor field-effect transistors have been const ructed with pentacene as the active semiconductor. The pentacene is pr ocessed by spin coating from a soluble precursor. A simple thermal con version yields transistors with carrier mobilities as high as 9 x 10(- 3) cm(2) V-1 s(-1) and current modulations of the order of 10(5). Depl etion of charge is essential to the device operation. Data for an inve rtor exhibiting voltage amplification are presented. (C) 1996 American Institute of Physics.
