Granular Electronic Systems
I. S. Beloborodov, K. B. Efetov, A. V. Lopatin +1
A granular metal is an array of metallic nano-particles imbedded into an insulating matrix. Tuning the intergranular coupling strength a granular system can be transformed into eit…
Hopping Transport in Granular Superconductors
A. V. Lopatin, V. M. Vinokur
We study the conductivity of granular superconductors in the weak coupling insulating regime. We show that it is governed by the hopping of either electrons or Cooper pairs dependi…
Coulomb effects and hopping transport in granular metals
I. S. Beloborodov, A. V. Lopatin, V. M. Vinokur
We investigate effects of Coulomb interaction and hopping transport in the insulator phase of granular metals and quantum dot arrays. We consider a spatially periodic as well as an…
Effective description of hopping transport in granular metals
I. S. Beloborodov, A. V. Lopatin, V. M. Vinokur +1
We develop a theory of a variable range hopping transport in granular conductors based on the sequential electron tunnelling through many grains in the presence of the strong Coulo…
Effects of fluctuations and Coulomb interaction on the transition temperature of granular superconductors
I. S. Beloborodov, K. B. Efetov, A. V. Lopatin +1
We investigate the suppression of superconducting transition temperature in granular metallic systems due to (i) fluctuations of the order parameter (bosonic mechanism) and (ii) Co…
Universal Description of Granular Metals at Low Temperatures: Granular Fermi Liquid
I. S. Beloborodov, A. V. Lopatin, V. M. Vinokur
We present a unified description of the low temperature phase of granular metals that reveals a striking generality of the low temperature behaviors. Our model explains the univers…
