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…
Non-linear electrical conduction and broadband noise in charge-ordered rare earth manganate Nd_0.5Ca_0.5MnO_3
Ayan Guha, Arindam Ghosh, A. K. Raychaudhuri +3
Measurements of the dc transport properties and the low-frequency conductivity noise in films of charge ordered Nd_0.5Ca_0.5MnO_3 grown on Si subtrate reveal the existence of a thr…
Universal conductance fluctuations in three dimensional metallic single crystals of Si
Arindam Ghosh, A. K. Raychaudhuri
In this paper we report the measurement of conductance fluctuations in single crystals of Si made metallic by heavy doping (n \approx 2-2.5n_c, n_c being critical composition at Me…
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…
Collapse of the charge ordering gap of Nd_{0.5}Sr_{0.5}MnO_{3} in an applied magnetic field
Amlan Biswas, Anthony Arulraj, A. K. Raychaudhuri +1
We report results of tunneling studies on the charge ordering compound Nd_{0.5}Sr_{0.5}MnO_{3} in a magnetic field up to 6T and for temperature down to 25K.We show that a gap (2Δ_{…
