Resistivity noise in crystalline magnetic nanowires and its implications to domain formation and kinetics
Amrita Singh, Debtosh Chowdhary, Arindam Ghosh
We have investigated the time-dependent fluctuations in electrical resistance, or noise, in high quality crystalline magnetic nanowires within nanoporous templates. The noise incre…
Highly enhanced thermopower in two-dimensional electron systems at milliKelvin temperatures
Srijit Goswami, Christoph Siegert, Matthias Baenninger +4
We report experimental observation of an unexpectedly large thermopower in mesoscopic two-dimensional (2D) electron systems on GaAs/AlGaAs heterostructures at sub-Kelvin temperatur…
Ultra-low noise field-effect transistor from multilayer graphene
Atindra Nath Pal, Arindam Ghosh
We present low-frequency electrical resistance fluctuations, or noise, in graphene-based field-effect devices with varying number of layers. In single-layer devices the noise magni…
