Optical conductivity of a granular metal at not very low temperatures
V. Tripathi, Y. L. Loh
We study the finite-temperature optical conductivity, sigma(omega,T), of a granular metal using a simple model consisting of a array of spherical metallic grains. It is necessary t…
Thermal transport in a granular metal array
V. Tripathi, Y. L. Loh
We obtain the Kubo formula for the electronic thermal conductivity kappa(T) of a granular metal array at low temperatures for the Ambegaokar-Eckern-Schoen (AES) model and study the…
Effective charging energy for a regular granular metal array
Y. L. Loh, V. Tripathi, M. Turlakov
We study the Ambegaokar-Eckern-Schön (AES) model for a regular array of metallic grains coupled by tunnel junctions of conductance and calculate both paramagnetic and diamagnet…
Coulomb blockade and quantum tunnelling in the low-conductivity phase of granular metals
V. Tripathi, M. Turlakov, Y. L. Loh
We study the effects of Coulomb interaction and inter-grain quantum tunnelling in an array of metallic grains using the phase-functional approach for temperatures well below th…
