About Picocoulombs per square metre

The picocoulomb per square metre (pC/m²) equals 10⁻¹² C/m², the scale for surface charge density on lightly charged polymer electret films and semiconductor surface states. Low-dose ion-implanted silicon has surface charge densities of 1-100 pC/m²; piezoelectric polymer films (PVDF) accumulate picocoulombs per square metre at low mechanical stress. 1 pC/m² = 10⁻¹² C/m² = 10⁻³ nC/m².

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.
