Abstract:
1. A method of forming a semiconductor film, comprising: coating or printing onto a substrate a composition that includes (i) a polysilane, a polygermane or a polysilagermane and (ii) a solvent in which the polysilane, polygermane or polysilagermane is soluble, wherein the polysilane, polygermane or polysilagermane consists essentially of blocks of —(AHR)—, —(—A irradiating said composition with UV radiation, simultaneously with or immediately subsequent to coating or printing said composition onto said substrate; heating said coated or printed composition sufficiently to remove volatile components and form an amorphous, hydrogenated semiconductor film; and annealing and/or irradiating said amorphous, hydrogenated semiconductor film sufficiently to at least partially crystallize and reduce a hydrogen content of said amorphous, hydrogenated semiconductor film and form said semiconductor film.
