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 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.
