Universal scaling in disordered systems and non-universal exponents
K. K. Bardhan, D. Talukdar, U. N. Nandi +1
The effect of an electric field on conduction in a disordered system is an old but largely unsolved problem. Experiments cover an wide variety of systems - amorphous/doped semicond…
Scaling of NonOhmic Conduction in Strongly Correlated Systems
D. Talukdar, U. N. Nandi, A. Poddar +2
A new scaling formalism is used to analyze nonlinear I-V data in the vicinity of metal-insulator transitions (MIT) in five manganite systems. An exponent, called the nonlinearity e…
Nonlinearity exponents in lightly doped Conducting Polymers
D. Talukdar, U. N. Nandi, K. K. Bardhan +4
The \textit{I-V} characteristics of four conducting polymer systems like doped polypyrrole (PPy), poly 3,4 ethylene dioxythiophene (PEDOT), polydiacetylene (PDA) and polyaniline (P…
Low noise constant current source for bias dependent noise measurements
D. Talukdar, R. K. Chakraborty, Suvendu Bose +1
A low noise constant current source used for measuring the noise in disordered systems in ohmic as well as non-ohmic regime is described. The source can supply low noise cons…
