Abstract

The invention provides a process for producing a layer of a semiconductor material, wherein the process comprises: a) disposing on a substrate: i) a plurality of particles of a semiconductor material, ii) a binder, wherein the binder is a molecular compound comprising at least one metal atom or metalloid atom, and iii) a solvent; and b) removing the solvent. The invention also provides a layer of semiconductor material obtainable by this process. In a preferred embodiment, the particles of a semiconductor material comprise mesoporous particles of the semiconductor material or mesoporous single crystals of the semiconductor material. The invention provides a process for producing a compact layer of a semiconductor material, wherein the process comprises: disposing on a substrate i) a solvent, and ii) a molecular compound comprising at least one metal or metalloid atom and one or more groups of formula OR, wherein each R is the same or different and is an unsubstituted or substituted C₁-C₈ hydrocarbyl group, and wherein two or more R groups may be bonded to each other; and b) removing the solvent. The invention also provides a compact layer of a semiconductor material obtainable by this process. These processes can be effectively performed at temperatures of less than 300° C. Further provided are semiconductor devices comprising either a layer of a semiconductor material or a compact layer of a semiconductor material obtainable by the processes of the invention. The invention also provides a process for producing a semiconductor device.
