    Abstract: One method disclosed herein includes forming a patterned mask layer above a surface of a semiconductor substrate, performing at least one etching process through the patterned mask layer to define a plurality of intersecting ridges that define a ridged surface in the substrate, and forming a Group III-V material on the ridged surface of the substrate. An illustrative device disclosed herein includes a Group IV substrate having a ridged surface comprised of a plurality of intersecting ridges and a Group III-V material layer positioned on the ridged surface of the Group IV substrate.

    Abstract: Methods are presented for fabricating nanowire structures, such as one or more nanowire field effect transistors. The methods include, for instance: providing a substrate and forming a fin above the substrate so that the fin has a first sidewall including one or more elongate first sidewall protrusions and a second sidewall including one or more elongate second sidewall protrusions, with the one or more elongate second sidewall protrusions being substantially aligned with the one or more elongate first sidewall protrusions; and, anisotropically etching the fin with the elongate first sidewall protrusions and the elongate second sidewall protrusions to define the one or more nanowires. The etchant may be chosen to selectively etch along a pre-defined crystallographic plane, such as the (111) crystallographic plane, to form the nanowire structures.
