Diamond has seen increased use in various fields in the past two decades due to its outstanding mechanical properties, wide optical transparency, and biocompatibility. Recent advances in methods for SCD nano-structuring have enabled the realization of micro- and nano-structures for a wide range of applications, including the controlled incorporation of optically active point defects such as nitrogen vacancy centers. Challenges in scaling up SCD nano-structure fabrication and its commercial applications are discussed, along with future prospects.
In the last two decades, the use of diamond as a material for applications in nanophotonics, optomechanics, quantum information, and sensors tremendously increased due to its outstanding mechanical properties, wide optical transparency, and biocompatibility. This has been possible owing to advances in methods for growth of high-quality single crystal diamond (SCD), nanofabrication methods and controlled incorporation of optically active point defects (e.g., nitrogen vacancy centers) in SCD. This paper reviews the recent advances in SCD nano-structuring methods for realization of micro- and nano-structures. Novel fabrication methods are discussed and the different nano-structures realized for a wide range of applications are summarized. Moreover, the methods for color center incorporation in SCD and surface treatment methods to enhance their properties are described. Challenges in the upscaling of SCD nano-structure fabrication, their commercial applications and future prospects are discussed.
