Scalable Parallel Single-Electron Pumps in Silicon with Split-Source Control in the Nanoampere Regime
Gento Yamahata, Takase Shimizu, Katsuhiko Nishiguchi +1
Parallelizing single-electron pumps offers a promising route to achieving nanoampere-level currents crucial for quantum current standard applications. Achieving such current levels…
High frequency breakdown in quantum dots
Nathan Johnson, Gento Yamahata, Akira Fujiwara
Dynamic quantum dots are known to generate very accurate currents and can be used as a source of single electron wavepackets for use in quantum metrology, sensing or information pr…
An ambipolar single-charge pump in silicon
Gento Yamahata, Akira Fujiwara
The mechanism of single-charge pumping using a dynamic quantum dot needs to be precisely understood for high-accuracy and universal operation toward applications to quantum current…
Advances toward high-accuracy gigahertz operation of tunable-barrier single-hole pumps in silicon
Gento Yamahata, Akira Fujiwara
Precise and reproducible current generation is key to realize quantum current standards in metrology. A promising candidate is a tunable-barrier single-charge pump, which can accur…
