Parallel Silicon Single-Electron Pumps for Generating Nanoampere Current
We demonstrate enhanced current generation in parallelized tunable-barrier single-electron pumps in silicon by optimizing operating conditions through individual source voltage control. Precise parallelization of three pumps yielded a record-high current exceeding 2 nA. This achievement represents progress toward ultra-high-precision current generation for quantum current standard applications.
