Cover Story: Doping diamond with boron, nitrogen or phosphorus enables a fine tuning of its electronic properties, which is particularly relevant for applications involving electron emission. However, the chemical nature of the doping sites and its correlation with electron emission properties remains to be clarified. In this work, we applied soft X-ray spectroscopy techniques to probe occupied and unoccupied electronic states in undoped, boron-, phosphorus-, and nitrogen-containing single crystal diamonds. X-ray absorption, X-ray emission, and X-ray photoemission spectroscopies, performed at the carbon K-edge, provide a full picture of new electronic states created by impurities in diamond. The different probing depth of fluorescence- and electron-based detection techniques enables a comparison between surface and bulk contributions. View this paper.
