yoctoampere

From yocto- +‎ ampere.

yoctoampere (plural yoctoamperes)

1. (metrology) An SI unit of electrical current equal to 10⁻²⁴ amperes. Symbol: yA

     However, in the IGZO-FET, heavy holes strongly suppress tunneling current, and at most yoctoampere off-state current is estimated which is dominated by thermally excited holes.

     First, they are known to show an off-state current on the order of yoctoampere per micron (10⁻²⁴ A/µm) at room temperature (RT).

   • 2018, Jun Koyama, Semiconductor device including refresh circuit for memory cell (UA Patent 9,922,692):

     For example, the off-state current per micrometer of the channel width at 85° C. is less than or equal to 100 yA (1 yA (yoctoampere) is 1×10⁻²⁴ A).
