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.
About Coulombs per square centimetre
The coulomb per square centimetre (C/cm²) equals exactly 10⁴ C/m², used in electrochemistry for Faradaic charge densities in electrolytic cells and battery electrode characterisation. The theoretical charge density for lithiation of a graphene anode monolayer is ≈ 0.38 C/cm²; proton exchange membrane fuel cell charge densities are 0.1-1 C/cm²; pulsed-laser ablation craters carry µC to mC per cm². 1 C/cm² = 10⁴ C/m².
