Abstract

The work provides a proof-of-concept demonstration of the room-temperature quantum current source based on nanoscale metal-oxide-semiconductor-Field-Effect-Transistor (MOSFET). Using low leakage MOSFET, the current pump achieved 1.00011 ± 0.00022 charges per cycle without any leakage correction scheme. The accuracy is limited by noise in the very low current measurement, and by calibration uncertainty.
