Title: | Toward Deep Blue Nano Hope Diamonds: Heavily Boron-Doped Diamond Nanoparticles | Authors: | Heyer, Steffen JANSSEN, Wiebke TURNER, Stuart Lu, Ying-Gang YEAP, Weng Siang Verbeeck, Jo HAENEN, Ken Krueger, Anke |
Issue Date: | 2014 | Publisher: | AMER CHEMICAL SOC | Source: | ACS NANO, 8 (6), p. 5757-5764 | Abstract: | The production of boron-doped diamond nanoparticles enables the application of this material for a broad range of fields, such as electrochemistry, thermal management, and fundamental superconductivity research. Here we present the production of highly boron-doped diamond nanoparticles using boron-doped CVD diamond films as a starting material. In a multistep milling process followed by purification and surface oxidation we obtained diamond nanoparticles of 10-60 nm with a boron content of approximately 2.3 x 10(21) cm(-3). Aberration-corrected HRTEM reveals the presence of defects within individual diamond grains, as well as a very thin nondiamond carbon layer at the particle surface. The boron K-edge electron energy-loss near-edge fine structure demonstrates that the B atoms are tetrahedrally embedded into the diamond lattice. The boron-doped diamond nanoparticles have been used to nucleate growth of a boron-doped diamond film by CVD that does not contain an insulating seeding layer. | Notes: | [Heyer, Steffen; Krueger, Anke] Univ Wurzburg, Inst Organ Chem, D-97074 Wurzburg, Germany.
