2014 MRS Spring Meeting


PP7.04 - Optical and Mechanical Characterization of Engineered Nanodiamond Structures


Apr 24, 2014 9:45am ‐ Apr 24, 2014 10:00am

Description

Our recent work in the measurements of and by carbon nanostructures, especially carbon nanotubes and graphene, provides a foundation upon which to build a vibrant nanodiamond program. NIST plans to harness the benefits of this unique, quantum mechanical system; nitrogen vacancy (NV) nanodiamond, to enable SI-traceable force, thermal and magnetic metrology. The luminescent NV impurity has been demonstrated as a magnetic and electrical fields and temperature sensor, and provides a possible vehicle for use in quantum information systems.

In this work, we describe novel methods for manipulating nanoscale diamond particles leveraging the tip of an atomic force microscope (AFM). Ultimately we plan to attach the nanodiamond to the tip to sense surfaces. The resulting nanostructures enable a platform to thoroughly study the optical properties the isolated nanodiamonds. Both resonant Raman and fluorescence spectroscopy are used to establish the quality and location of the NV centers. Ultimate goals include the combination of mechanical and optical characterization for tip-enhanced Raman spectroscopy and torsional AFM measurements.
