In-Memory AM Demodulation Using an All-Silicon Independent-Dual-Gate Gain-Cell Memory with A Leakage Determined by Single-Electron Counting
Katsuhiko Nishiguchi, Toshiaki Hayashi, Kensaku Chida +3
Ultra-low-leakage memories are attracting increasing attention for in-memory sensing and computing. However, achieving sufficiently long retention in silicon memories for analog si…
Coulomb-mediated single-electron heat transfer statistics across capacitively coupled silicon nanodots
Kensaku Chida, Antoine Andrieux, Katsuhiko Nishiguchi
Heat transfer mediated by the Coulomb interaction reveals unconventional thermodynamic behavior and broadens thermodynamics research into fields such as quantum dynamics and inform…
Experimental Proof of Universal Conductance Fluctuation in Quasi-1D Epitaxial BiSe Wires
Sadashige Matsuo, Kensaku Chida, Daichi Chiba +8
We report on conductance fluctuation in quasi-one-dimensional wires made of epitaxial BiSe thin film. We found that this type of fluctuation decreases as the wire lengt…
Low-frequency and shot noises in CoFeB/MgO/CoFeB magnetic tunneling junctions
Tomonori Arakawa, Takahiro Tanaka, Kensaku Chida +7
The low-frequency and shot noises in spin-valve CoFeB/MgO/CoFeB magnetic tunneling junctions were studied at low temperature. The measured 1/f noise around the magnetic hysteresis…
Observation of finite excess noise in the voltage-biased quantum Hall regime as a precursor for breakdown
Kensaku Chida, Tomonori Arakawa, Sadashige Matsuo +7
We performed noise measurements in a two-dimensional electron gas to investigate the nonequilibrium quantum Hall effect (QHE) state. While excess noise is perfectly suppressed arou…
Signature of Coherent Transport in Epitaxial Spinel-based Magnetic Tunnel Junctions Probed by Shot Noise Measurement
Takahiro Tanaka, Tomonori Arakawa, Kensaku Chida +7
We measured the shot noise in fully epitaxial Fe/MgAl2OX/Fe-based magnetic tunneling junctions (MTJs). While the Fano factor to characterize the shot noise is very close to unity i…
