Abstract
A process for making a nanoduct includes: disposing an etchant catalyst on a semiconductor substrate including a single crystal structure; heating the semiconductor substrate to an etching temperature; introducing an oxidant; contacting the semiconductor substrate with the oxidant in a presence of the etchant catalyst; anisotropically etching the semiconductor substrate by the etchant catalyst in a presence of the oxidant in an etch direction that is coincident along a crystallographic axis of the semiconductor substrate; and forming the nanoduct as the etchant catalyst propagates along a surface of the semiconductor substrate during anisotropically etching the semiconductor substrate, the nanoduct being crystallographically aligned with the crystallographic axis of the semiconductor substrate.
