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 Abfarads
The abfarad (abF) is the capacitance unit of the CGS-EMU system, equal to 1 abC / 1 abV = 10 C / 10⁻⁸ V = 10⁹ F, exactly equal to 1 GF in SI. It appeared in nineteenth-century and early twentieth-century electromagnetic engineering texts alongside abohms and abamperes; 1 abF represents the capacitance of a connection storing 10 C at 10 nV. 1 abF = 10⁹ F = 1 GF.
