Abstract: Apparatus for nanofabrication on an unconventional substrate including a patterned pliable membrane mechanically coupled to a membrane support structure, a substrate support structure to receive a substrate for processing, and an actuator to adjust the distance between the pliable membrane and the substrate. Nanofabrication on conventional and unconventional substrates can be achieved by transferring a pre-formed patterned pliable membrane onto the substrate using a transfer probe or non-stick sheet, followed by irradiating the substrate through the patterned pliable membrane so as to transfer the pattern on the pliable membrane into or out of the substrate. The apparatus and methods allow fabrication of diamond photonic crystals, fiber-integrated photonic devices and Nitrogen Vacancy (NV) centers in diamonds.

Abstract: Techniques for fabricating diamond nanostructures including application of a self-assembled hard mask to a surface of a diamond substrate to define a pattern of masked regions having a predetermined diameter surrounded by an exposed portion. The exposed portion can be vertically etched to a predetermined depth using inductively coupled plasma to form a plurality of nanoposts corresponding to the masked regions. The nanoposts can be harvested to obtain a nanostructure with a diameter corresponding to the predetermined diameter and a length corresponding to the predetermined depth.
