• illumination source. In other words, in this test, pp-KPFM is not used to perform a time-resolved measurement as a function of Δt. It is rather used to monitor a SP at two different levels of illumination, namely in a dark state and under cw illumination. Neglecting noise, both configurations yielded identical

To record the time evolution of the NV intensity during switching between NV− or

Upon applying a higher reverse bias potential (+20 V) we detect a spectrum of NV− emission (blue spectrum). Schematic setup for time-resolved measurement of NV-intensity. To record the time

A time-resolved measurement of NV− (red curve) and NV0 (black curve) intensity simultaneously during switching between NV− and NV+ shows that the charging and
