“…In diamond, the frequency of the extracted k should correspond to the timing related to the fast electron transport in the conduction band (ε r ~5.5) and not to the static dielectric response (ε r ~7.8). In fact, in literature relative to the FP effect for diamond samples, it is typically found that a value for the exponential coefficient of about 3.2 × 10 −4 eVcm/V, properly corresponding to an ε r = 5.5 [ 41 , 42 ], even though higher values have been found under irradiation [ 43 ].…”

A recent innovation in diamond technology has been the development of the “black diamond” (BD), a material with very high optical absorption generated by processing the diamond surface with a femtosecond laser. In this work, we investigate the optical behavior of the BD samples to prove a near to zero dielectric permittivity in the high electric field condition, where the Frenkel-Poole (FP) effect takes place. Zero-epsilon materials (ENZ), which represent a singularity in optical materials, are expected to lead to remarkable developments in the fields of integrated photonic devices and optical interconnections. Such a result opens the route to the development of BD-based, novel, functional photonic devices.

“…The effective capacitance C eff (ω) is the capacitance of the two layers of dielectric materials, equivalently to the diamond and the protective layer in series. The material parameters used in our calculations are taken from the literature [63] and are shown in Table I. At low frequencies the noise spectra exhibit white noise, with a transition at higher frequencies to a power law spectrum, with S (ω) ∝ 1/f a .…”

Surface noise is a detrimental issue for sensing devices based on shallow nitrogen vacancy (NV) color center diamonds. A recent experiment indicates that electric field noise is significant compared to magnetic field noise. They also found that the electric field noise can be reduced with a protective surface layer, though the mechanism of noise reduction is not well understood. We examine the effect of a protective surface layer on the noise spectrum, which is caused by surface charge fluctuations. We use the fluctuation-dissipation theorem to calculate and analyze the noise spectrum for six different surface layer materials typically used for NV center diamond devices. We find that four parameters largely affect the noise spectrum: effective relaxation time, effective loss tangent, power law exponent of the noise spectrum, and layer thickness. Our results suggest that a surface covering layer is indeed useful for decreasing surface noise, but which material is most suitable depends on the device operational frequency range.
