About Attofarads
The attofarad (aF) equals 10⁻¹⁸ F, the scale for quantum-mechanical and nanoscale capacitances. Carbon-nanotube transistor gate capacitances are 1-100 aF; single-electron tunnel junctions in Coulomb-blockade devices operate in the attofarad range; scanning-probe microscopy tip-sample junctions at sub-nanometre separation approach 1 aF. 1 aF = 10⁻³ fF = 10⁻¹⁸ F.
About Statfarads
The statfarad (statF) is the capacitance unit of the CGS-Gaussian system, equal to exactly 10⁵/c² F where c = 299 792 458 m/s, giving ≈ 1.1127 × 10⁻¹² F. A sphere of 1 cm radius in vacuum has capacitance exactly 1 statF in Gaussian units; Gaussian-system electrostatics texts and plasma-physics codes express capacitances in statfarads. 1 statF = 10⁵/c² F ≈ 1.113 pF.
