Abstract:
1. A method of making nanowires comprising: providing a semiconductor layer on a dielectric layer, wherein the semiconductor layer comprises one or more openings with each opening having a plurality of semiconductor sidewalls and exposing a portion of the underlying dielectric layer; forming a selective growth mask on at least two of the semiconductor sidewalls, wherein the selective growth mask comprises one or more patterned apertures with each patterned aperture exposing a portion of the underlying semiconductor sidewall; growing a semiconductor material on the portion of the semiconductor sidewall that is exposed in each patterned aperture to form a nanowire having a constant cross-sectional feature; and forming a nanowire network by continuing to grow the nanowire, wherein adjacent nanowires on different sidewalls of the at least two of the semiconductor sidewalls merge into one or more nanowire branches.
