About Attocoulombs per square metre

The attocoulomb per square metre (aC/m²) equals 10⁻¹⁸ C/m², the scale for areal charge density on individual molecular monolayers measured by Kelvin probe force microscopy. A single elementary charge on a 1 µm² area gives about 0.16 aC/m²; contact potential distributions in organic photovoltaic blends correspond to aC/m²-scale surface charge. 1 aC/m² = 10⁻¹⁸ C/m² = 10⁻³ fC/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.
