Effect of fluorinated diamond surface on charge state of nitrogen-vacancy centers (1304.1407v1)
Published 4 Apr 2013 in cond-mat.mtrl-sci
Abstract: We investigated the effect of fluorine-terminated diamond surface on the charged state of shallow nitrogen vacancy defect centers (NVs). Fluorination is achieved with CF4 plasma and the surface chemistry is confirmed with x-ray photoemission spectroscopy. Photoluminescence of these ensemble NVs reveal that fluorine-treated surfaces lead to a higher negatively charged nitrogen vacancy (NV-) population than oxygen-terminated surfaces. Using surface chemistry to control NV charges, in particular increasing the density of NV- centers, is an important step towards improving the optical and spin properties of NVs for quantum information processing and magnetic sensing.
