Resistance fluctuations and 1/f noise in single crystalline Ni nanowires
Sudeshna Samanta, M. Venkata Kamalakar, A. K. Raychaudhuri
We measured the low frequency (10mHz < f < 10Hz) resistance fluctuations (Noise) in single crystalline ferromagnetic Ni nanowires (diameter ~35nm) in the temperature range 80K-300K…
Temperature dependent electrical resistivity of a single strand of ferromagnetic single crystalline nanowire
M. Venkata Kamalakar, A. K. Raychaudhuri, Xueyong Wei +2
We have measured the electrical resistivity of a single strand of a ferromagnetic Ni nanowire of diameter 55 nm using a 4-probe method in the temperature range 3 K-300 K. The wire…
Temperature dependence of the resistance of metallic nanowires (diameter 15 nm): Applicability of Bloch-Grüneisen theorem
Aveek Bid, Achyut Bora, A. K. Raychaudhuri
We have measured the resistances (and resistivities) of Ag and Cu nanowires of diameters ranging from 15nm to 200nm in the temperature range 4.2K-300K with the specific aim to asse…
1/f noise in nanowires
Aveek Bid, Achyut Bora, A. K. Raychaudhuri
We have measured the low-frequency resistance fluctuations (1 mHz<f<10 Hz) in Ag nanowires of diameter 15 nm<d<200 nm at room temperatures. The power spectral density (PSD) of the…
Low frequency conductance fluctuations (1/f^αnoise) in 15nm Ag nanowires: Implication on its stability
Aveek Bid, Achyut Bora, A. K. Raychaudhuri +1
We have measured the low frequency (1mHz<f<10Hz) resistance fluctuations in metallic nanowires (diameter 15nm to 200nm) in the temperature range 77K to 400K. The nanowires were gro…
Electric field induced suppression of universal conductance fluctuations and dephasing in disordered systems
Arindam Ghosh, A. K. Raychaudhuri
We report a novel phenomenon that the universal conductance fluctuations (UCF) can be suppressed by a small electric field E. The experiment has been carried out on single crystals…
