About Statcoulombs per square centimetre
The statcoulomb per square centimetre (statC/cm²) is the surface charge density unit of the CGS-Gaussian system, equal to 10³/c C/m² where c = 299 792 458 m/s, giving ≈ 3.336 × 10⁻⁶ C/m². In Gaussian units Gauss's law reads E = 4πσ (no ε₀ factor); 1 statC/cm² produces a surface field of 4π statV/cm. 1 statC/cm² ≈ 3.336 µC/m².
About Femtocoulombs per square metre
The femtocoulomb per square metre (fC/m²) equals 10⁻¹⁵ C/m², arising in scanning Kelvin probe measurements of oxide fixed charge. MOS interface state densities of 10¹ charges/cm² correspond to about 0.16 fC/m²; fixed charge in high-k gate dielectrics and SiO₂/Si interfaces is typically 10-100 fC/m². 1 fC/m² = 10⁻¹⁵ C/m² = 10⁻³ pC/m².
