By combining laser interference lithography and metal-assisted etching we were able to produce arrays of silicon nanowires with uniform diameters as small as 65 nm and densities exceeding 2 × 107 mm − 2. The wires are single crystalline, vertically aligned, arranged in a square pattern and obey strict periodicity over several cm2. The applied technique allows for a tailoring of nanowire size and density. Using a controlled and scalable process to fabricate sub-100 nm silicon nanowires is an…
