Abstract

A method for depositing a Group IV semiconductor on a surface of a substrate is disclosed. The method may include: providing a substrate within a reaction chamber and heating the substrate to a deposition temperature. The methods may further include: exposing the substrate to at least one Group IV precursor and exposing the substrate to at least one Group IIIA dopant precursor; wherein the at least one Group IIIA dopant precursor comprises a borohydride, an organic borohydride, a halide, or an organohalide. Semiconductor device structures including a Group IV semiconductor deposited by the methods of the disclosure are also provided.
