Criticality of tuning in athermal phase transitions
U. Chandni, Arindam Ghosh, H. S. Vijaya +1
We experimentally address the importance of tuning in athermal phase transitions, which are triggered only by a slowly varying external field acting as tuning parameter. Using high…
Observation of non-gaussian conductance fluctuations at low temperatures in Si:P(B) at the metal-insulator transition
Swastik Kar, A. K. Raychaudhuri, Arindam Ghosh
We report investigations of conductance fluctuations (noise) in doped silicon at low temperatures (TK) as it is tuned through the metal-insulator transition (MIT). The scaled…
Conductance fluctuations near Anderson transition
Arindam Ghosh, A. K. Raychaudhuri
In this paper we report measurements of conductance fluctuations in single crystal samples of Si doped with P and B close to the critical composition of the metal insulator transit…
Kinetics of electric field induced oxygen ion migration in epitaxial metallic oxide films
Arindam Ghosh, A. K. Raychaudhuri, R. Sreekala +2
In this paper we report the observation of curent induced change of resistance of thin metallic oxide films. The resistance changes at a very low current (current density $J \geq 1…
