Fields of scientific research: Material technologies


The long term goal of the project is to develop novel nanoscale sensors, computation elements, and lithographic techniques using the quantum optical properties of diamond color centers. To accomplish this, a number of diamond color centers will be investigated including some unpublished and recently published. To simplify comparison of different color centers for the intended applications a common testbed will designed and constructed which consists of a microscope system optimized to probe a thin, shallow layer of color centers in a bulk diamond. This approach will allow the color centers to be close to the surface, as required for sensing, super-resolution imaging/lithography and some computing element applications, yet ensures that the surround diamond is of high quality. To create the thin layers of color centers, bulk diamonds will be implanted and/or over-growth, followed by annealing and other post-processing when necessary. To facilitate these applications, techniques to eliminate the need for direct microwave excitation of the spin coherences will be explored, for example by identifying promising color centers for optical Raman excitation of spin coherences at temperatures approaching ambient.
