Abstract
Section titled āAbstractāAbstract We demonstrated the correlation spectroscopy of organosilane monolayers using an ensemble of shallow nitrogen-vacancy centers as the quantum sensor. Several types of organosilane monolayers were grown directly on the diamond surface by exposing the surface to a silane precursor vapor. The feasibility of detecting 1 H and 19 F in the monolayer was examined by correlation spectroscopy measurements. The effect of the magnetic dipole-dipole interaction on the peak width was also discussed by comparing the spectrum of the monolayer with that of surface-attached 1 H and that of immersion oil. The results highlight the feasibility of nitrogen-vacancy centers as the spin probe for physicochemical analyses of monolayers grown on the diamond surface.
