Abstract:
Various nanostructures, including silicon nanowires and encapsulated silicon nanoislands, and methods of making the nanostructures are provided. The methods can include providing a fin structure extending above a substrate, wherein the fin structure has at least one silicon layer and at least two silicon:germanium alloy (SiGe) layers that define sidewalls of the fin structure; and annealing the fin structure in oxygen to form a silicon nanowire assembly. The silicon nanowire assembly can include a silicon nanowire, a SiGe matrix surrounding the silicon nanowire; and a silicon oxide layer disposed on the SiGe matrix. The annealing can be, for example, at a temperature between 800° C. and 1000° C. for five minutes to sixty minutes. The silicon nanowire can have a long axis extending along the fin axis, with perpendicular first and second dimensions extending less than 50 nm along directions perpendicular to the fin axis.

Claim (Index 1):
A device comprising:\n a substrate, and a nanostructure, the nanostructure comprising:\n a fin structure disposed on the substrate, the fin structure having a fin axis, wherein the fin structure comprises: \n at least one silicon nanowire having a long axis extending along the fin axis, the at least one silicon nanowire comprising monocrystalline silicon; and \n a matrix material surrounding the nanowire, the matrix material comprising a monocrystalline silicon:germanium alloy (SiGe), \n wherein the at least one silicon nanowire has a first dimension extending less than 50 nm along a first direction perpendicular to the fin axis, and a second dimension extending less than 50 nm along a second direction perpendicular to the first direction and the fin axis, wherein the fin structure has an outer surface comprising SiGe material, and wherein the at least one silicon nanowire does not extend on the outer surface of the fin structure.
