Increased negatively charged nitrogen-vacancy centers in fluorinated diamond

Shanying Cui, Evelyn L. Hu

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 reveals that fluorine-treated surfaces lead to a higher and more stable negatively charged nitrogen vacancy (NV−) population than oxygen-terminated surfaces. NV− population is estimated by the ratio of negative to neutral charged NV zero-phonon lines. Surface chemistry control of NV− density is an important step towards improving the optical and spin properties of NVs for quantum information processing and magnetic sensing.

Conversion of neutral nitrogen-vacancy centers to negatively charged nitrogen-vacancy centers through selective oxidation

Kai‐Mei C. Fu, Charles Santori, Paul E. Barclay +1 more

The conversion of neutral nitrogen-vacancy centers to negatively charged nitrogen-vacancy centers is demonstrated for centers created by ion implantation and annealing in high-purity diamond. Conversion occurs with surface exposure to an oxygen atmosphere at 465 °C. The spectral properties of the charge-converted centers are investigated. Charge state control of nitrogen-vacancy centers close to the diamond surface is an important step toward the integration of these centers into devices for quantum information and magnetic sensing applications.
