Abstract:
1. A composition, comprising: a) one or more semiconductor precursors selected from the group consisting of (poly)silanes, (poly)germanes, and (poly)germasilanes in an amount of from 1 to 40% by weight, wherein at least 75 mmol % of said (poly)silanes, (poly)germanes, and (poly)germasilanes consist essentially of species having (i) from 15 to about 1,000,000 silicon and/or germanium atoms and (ii) hydrogen, and said (poly)silanes, (poly)germanes, and (poly)germasilanes are prepared by catalytic polymerization and subsequent removal of catalyst from said (poly)silanes, (poly)germanes, and (poly)germasilanes; and b) a solvent in which the one or more semiconductor precursors is soluble, wherein the composition has a viscosity of from 2 to 100 cP.
