Diamond : an experimental determination of diamond nucleation, nuclear magnetic resonance spectroscopy of diamondoids, and development of a novel technique for color center fabrication
Abstract/Contents
- Abstract
- Diamond is a useful material with numerous applications, classically owing to its high hardness and strength as a material. However as the understanding of the material has deepened and diamond nanomaterials have been further developed, new applications have been developed such as diamond electronics, magnetometry, and quantum computing. In this work, we utilize several methods to gain a more atomistic understanding of diamond. First, through the use of diamondoid seeds, diamond nanoparticles of known size and shape, the nucleation landscape of diamond growth during chemical vapor deposition (CVD) was experimentally determined. By measuring the resultant nanoparticle density after seeded growths, the critical nucleus size and interfacial energy were calculated and found to be orders of magnitude lower than classical predictions. Secondly, nuclear magnetic resonance (NMR) spectroscopy was performed on pentamantane isomers. NMR results on these diamondoid molecules were able to reveal effects to the electronic structure due to non-covalent interactions that could have important implications for diamond surfaces and surface defects. Lastly, a novel technique for generating nitrogen-vacancy (NV) centers in diamond was demonstrated. Through the use of metal vacancy-injection (VI) films, vacancies were able to be doped into diamond substrates to enhance the NV center density. Furthermore, it was shown that through patterning of these VI films, the areas of vacancy doping and resulting NV centers could be patterned in the diamond substrate. This technique offers a reliable and scalable method to create high-quality color centers while limiting lattice damage.
