Helium-Gas-Cooled Cryogenic Current Comparator Integrated with a Quantum Resistance Standard
Yuma Okazaki, Takehiko Oe, Nobu-Hisa Kaneko
We report a cryogen-free cryogenic current comparator (CCC) system for precision resistance measurements. A helium-gas chamber was developed and installed on the 4 K stage of a cry…
Suppression of Electromagnetic Crosstalk by Differential Excitation for SAW Generation
Shunsuke Ota, Yuma Okazaki, Shuji Nakamura +6
Surface acoustic waves (SAWs) hold a vast potential in various fields such as spintronics, quantum acoustics, and electron-quantum optics, but an electromagnetic wave emanating fro…
On-Demand Single-Electron Source via Single-Cycle Acoustic Pulses
Shunsuke Ota, Junliang Wang, Hermann Edlbauer +10
Surface acoustic waves (SAWs) are a reliable solution to transport single electrons with precision in piezoelectric semiconductor devices. Recently, highly efficient single-electro…
Quantum mechanical current-to-voltage conversion with quantum Hall resistance array
Dong-Hun Chae, Mun-Seog Kim, Wan-Seop Kim +2
Accurate measurement of the electric current requires a stable and calculable resistor for an ideal current to voltage conversion. However, the temporal resistance drift of a physi…
