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 Nanoamperes
The nanoampere (nA) equals 10⁻⁹ A, typical for reverse saturation currents of silicon diodes, quiescent supply currents of CMOS logic, and microelectrode measurements in analytical electrochemistry. A silicon p-n junction at room temperature has a saturation current of 1-10 nA; a well-designed op-amp input bias current is 1-100 nA; wearable biosensors commonly operate in the nanoampere range. 1 nA = 10⁻³ µA = 10³ pA.
