The most significant experimental results and theoretical concepts related to chromium
dioxide-based composites, according to their influence on the evolution of modern …

Temperature and magnetic field dependencies of resistance for functionalized multiwall
carbon nanotubes (MWCNTs) have been studied. The measurements were carried out in …

The magnetoresistance of bulk specimens of graphite nanoplatelets obtained by different
methods is studied in magnetic fields up to 2.2 T. It has been established that …

The unusual non-linear effects in hopping conduction of single-crystal La 2 CuO 4+ δ with
excess oxygen has been observed. The resistance is measured as a function of the applied …

We propose a new mechanism of negative magnetoresistance in non-magnetic granular
materials in which electron transport is dominated by hopping between two nearest …

The magneto-quantum and quantum interference effects in a two-dimensional gas of p-type
charge carriers are studied for three quantum wells made of practically pure germanium in a …

Granular superconductivity effects in a polycrystalline sample of ruthenocuprate RuSr2
(Gd1. 5Ce0. 5) Cu2O10− δ are studied. The main attention has been devoted to …

The results of the in-plane transport measurements of strongly underdoped La 2− x Sr x CuO
4 films in magnetic fields up to 14 T and at temperatures down to 1.6 K are presented. While …

A gold film (mean thickness≈ 3.5 nm) was deposited in high vacuum on a single-crystal
sapphire substrate at a temperature of 70 K. The transport properties of the film at low …

We present transport properties of quench-condensed Au film with nominal thickness≈ 3.56
nm and R□≈ 5 k Ω for T> 10 K. This film has weak nonmetallic temperature dependence of …
