We report electrical transport experiments, using the phenomenon of electrical breakdown to perform thermometry, that probe the thermal properties of individual multiwalled carbon nanotubes. Our results show that nanotubes can readily conduct heat by . . .

We study Coulomb blockade effects in the thermodynamic quantities of a weakly disordered metallic grain coupled to a metallic lead by a tunneling contact with a large conductance gT. We consider the case of broken time-reversal symmetry and obtain exp . . .

Composite multiferroics are materials exhibiting the interplay of ferroelectricity, magnetism, and strong electron correlations. Typical example--magnetic nano grains embedded in a ferroelectric matrix. Coupling of ferroelectric and ferromagnetic degr . . .

We study the electron transport in semiconducting nanocrystal arrays at temperatures T<<Ec, where Ec is the charging energy for a single grain. In this temperature range, the electron transport is dominated by cotunneling processes. We discuss both el . . .

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 universality of the low-temperature conductivity that coincides exactly with t . . .

We study electron transport in composite ferroelectrics -- materials consisting of metallic grains embedded in a ferroelectric matrix. Due to its complex tunable morphology the thermodynamic properties of these materials can be essentially different f . . .

We study thermoelectric properties of inhomogeneous nanogranular materials for weak tunneling conductance between the grains, gt<1. We calculate the thermopower and figure of merit taking into account the shift of the chemical potential and the asymme . . .

We present a comprehensive investigation into disorder-mediated charge transport in InP nanowires in the statistical doping regime. At zero gate voltage, transport is well described by the space charge limited current model and hopping transport, but . . .

We study the tunneling transport through a mesoscopic tunnel junction in the far-from-equilibrium regime at relatively low temperatures. We show that the current-voltage characteristics are significantly modified as compared to the usual quasiequilibr . . .

Inspired by a recent experiment, we study the influence of thermal fluctuations on the I-V characteristics of a Josephson junction, coupled to a strongly resistive environment. We obtain analytical results in the limit where the Josephson energy is la . . .
