Finite shot noise and electron heating at quantized conductance in high-mobility quantum point contacts
Tatsuya Muro, Yoshitaka Nishihara, Shota Norimoto +8
We report a precise experimental study on the shot noise of a quantum point contact (QPC) fabricated in a GaAs/AlGaAs based high-mobility two-dimensional electron gas (2DEG). The c…
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…
