| Abstract Scope |
Diamond is a wide band gap semiconductor displaying novel properties for applications in quantum systems. Especially, there is significant interest in diamond-containing nitrogen-vacancy (N-V) and silicon-vacancy (Si-V) defect centers with unusual optical emission characteristics for applications in quantum systems for quantum memory and sensing. The challenge for some of these applications requires the processing of high-quality diamond crystals containing N-V or Si-V defect centers for the greatest sensitivity. Understanding diamond nucleation mechanisms and incorporating N or Si dopants are critical to meeting this challenge, which is being studied. The processing approaches to synthesize N- and Si-doped diamond single crystals containing these defect centers by Microwave Plasma Enhanced Chemical Vapor Deposition are explored. The diamond crystals are characterized by Scanning Electron Microscopy (SEM), Raman, and Photoluminescence (PL) spectroscopies. These results and a brief overview of the promise of diamond for quantum applications will be presented and discussed. |
