| contents | Surface electric (charge) noise influences spin defects due to fluctuation of the surface charge density and also the electrostatic potential at the crystal surface. Surprisingly, the two-point correlation function of both the charged particles' positions and the surface electrostatic potential strongly influences the power of the polynomial decay of the electric noise spectral density; this power is not determined solely by the character of the charge fluctuators. Time-dependent crossover behavior near the correlation time of the fluctuators, of the spin defect's relaxation and decoherence, provide a quantitative fingerprint of the diffusive behavior of charged particles at the surface. |
