Granular metals are arrays of metallic particles of a size ranging usually from a few to
hundreds of nanometers embedded into an insulating matrix. Metallic granules are often …

Printed electronics using inks based on graphene and other two-dimensional materials can
be used to create large-scale, flexible and wearable devices. However, the complexity of ink …

We theoretically investigate the anomalous Hall effect in a system of dense-packed
ferromagnetic grains in the metallic regime. Using the formalism recently developed for the …

We study exchange coupling due to the interelectron Coulomb interaction between two
ferromagnetic grains embedded into an insulating matrix. This contribution to the exchange …

We study electron transport properties of composite ferroelectrics—materials consisting of
metallic grains embedded in a ferroelectric matrix. In particular, we calculate the conductivity …

We suggest to use “fluctuation spectroscopy “as a method to detect granularity in a
disordered metal close to a superconducting transition. We show that with lowering …

We investigate the interference correction to the conductivity of a medium consisting of
metallic grains connected by tunnel junctions. Tunneling conductance between the grains, e …

We present a theory of the Hall effect in dense-packed granular systems at large tunneling
conductance g T⪢ 1 (metallic regime). The Hall transport is essentially determined by the …

Combining scattering-matrix formalism with nonlinear σ-model technique we analyze weak

We perform a detailed calculation of the various contributions to the fluctuation conductivity
of a granular metal close to its superconducting transition. We find three distinct regions of …
