| Abstract Scope |
Diamond is a unique wide band gap semiconductor displaying optical transparency, high thermal conductivity, and dielectric properties. There is a significant interest in diamond containing nitrogen-vacancy (N-V) defect centers with unusual characteristics making it attractive for unique applications in quantum systems such as for quantum memory and sensing. The challenge for some of these applications requires processing of high- quality nitrogen-doped diamond crystals containing preferably only one type of N-V defects for greatest sensitivity. An understanding of diamond nucleation mechanism is critical for meeting this challenge, which is being studied. We are developing processing approaches to synthesize nitrogen-doped diamond single crystal containing N-V defect centers by Microwave Plasma Enhanced Chemical Vapor Deposition (MPECVD). The diamond crystals synthesized by MPECVD are characterized by Scanning Electron Microscopy (SEM), and Raman spectroscopy. These results along with a brief overview on the promise of diamond for quantum applications will be presented and discussed. |
