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 Kilofarads
The kilofarad (kF) equals 10³ F, reached only by large supercapacitor assemblies for energy buffering. Industrial supercapacitor modules for tram and metro regenerative braking are rated 500-10 000 F = 0.5-10 kF; hybrid-bus energy buffers stack 3 000 F cells to achieve several kilofarads; grid fast-response voltage-stabilisation banks are discussed in the kilofarad range. 1 kF = 10³ F = 10⁻³ MF.
