Nitrogen-vacancy centers in diamond are considered to be promising building blocks for emerging quantum technologies. At the same time, practical applications require them to be excited and controlled electrically. However, there is a lack of knowledge about their behavior in electrical driven systems. Here, we introduce a physical model to address the single-photon emission dynamics of electrically pumped NV center in diamond in a quantitative manner and present a detailed study of the single-photon emitting diode based on NV centers.
