“…Diamond has promising applications in a number of areas such as biomedical engineering [1], photonics [2], electrochemistry [3], and the cutting tools industry [4] owing to its high hardness, high Young's modulus, high thermal conductivity [5], tunable electrical conductivity [6], and bioinertness/biocompatibility [7], among others. The manufacture of miniature functional diamond structures, including diamond nanowires [8], nanopillars [9], micropillars [10], and pyramids [11] and arrays thereof, has attracted significant attention in the fields of nanoscale quantum sensing, photonic systems, scanning probes, and electrochemical sensors [12].…”

Diamond nanostructures are mostly produced from bulk diamond (single- or polycrystalline) by using time-consuming and/or costly subtractive manufacturing methods. In this study, we report the bottom-up synthesis of ordered diamond nanopillar arrays by using porous anodic aluminium oxide (AAO). Commercial ultrathin AAO membranes were adopted as the growth template in a straightforward, three-step fabrication process involving chemical vapor deposition (CVD) and the transfer and removal of the alumina foils. Two types of AAO membranes with distinct nominal pore size were employed and transferred onto the nucleation side of CVD diamond sheets. Subsequently, diamond nanopillars were grown directly on these sheets. After removal of the AAO template by chemical etching, ordered arrays of submicron and nanoscale diamond pillars with ~325 nm and ~85 nm diameters were successfully released.
