A crystalline CuInTe2 film is used as the channel layer in a thin-film field-effect transistor (see figure) yielding field-effect mobilities of over 10 cm2 V-1 s-1, which is approximately an order of magnitude better than previous results for spin-coated p-type systems. A novel three-component hydrazine-based solution is employed to achieve spin coating of the CuInTe2 film.
