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 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.
