About Attoamperes
The attoampere (aA) equals 10⁻¹⁸ A, the scale of single-electron tunnelling currents in quantum devices. Individual electrons tunnelling through a molecular junction or quantum dot produce average currents of order 1-100 aA when measured at sub-microsecond resolution; cryogenic shot-noise electrometers achieve sub-attoampere sensitivity. 1 aA = 10⁻³ fA = 10⁻¹⁸ A.
About Statamperes
The statampere (statA) is the current unit of the CGS-Gaussian system, equal to 1 statC/s = 1/(10c) A ≈ 3.336 × 10⁻¹⁰ A (exact, since c = 2.997 924 58 × 10⁸ m/s is exact). Two long parallel wires each carrying 1 statA and separated by 1 cm experience a force of 1/c² dyn per centimetre. The statampere is used in electrostatics texts where Coulomb's law is written without ε₀. 1 statA ≈ 333.6 pA.
