Memory Effect in the Charge Transport in Strongly Disordered Antimony Films
We study conductivity of strongly disordered amorphous antimony films under high bias voltages. We observe non-linear current-voltage characteristic, where the conductivity value at zero bias is one of two dis...

Nonuniform Quantum-Confined States and Visualization of Hidden Defects in Pb(111) Films
The spatial dependence of the differential conductivity of ultrathin Pb films deposited on the Si(111)7 × 7 surface has been studied by low-temperature scanning tunneling microscopy and spectroscopy. Pb films ...

Ab Initio Modeling of the Local Violation of a Peierls Transition at the Sb(111) Surface
The crystal structure of the Sb(111) surface is studied within the density functional theory. It is shown that a defect near-surface region with a thickness of 6–8 atomic layers, which is similar to a topologi...

Surface origin of quasi-2D Shubnikov–de Haas oscillations in Bi2Te2Se
Transport measurements at liquid helium temperatures were done on a number of Bi2Te2Se samples with thicknesses ranging from 30 to 200 μm in order to detect surface states. In each sample we observed Shubnikov–de...

Rotation dynamics of C60 molecules in a monolayer fullerene film on the WO2/W(110) surface near the rotational phase transition
The rotation dynamics of C60 molecules in monolayer fullerene films grown on the WO2/W(110) surface is studied by scanning tunneling microscopy. The formation of molecule clusters, which have a high libron vibrat...

Focusing of electrons by a transverse magnetic field
The foundations of the focusing of electrons by a transverse magnetic field proposed by V.S. Tsoi in 1974 have been reviewed. The kinetics of electrons in condensed media and interactions of conduction electro...

Atomic structure of the Cu(410)-O surface: STM visualization of oxygen and copper atoms
The structure of the Cu(410)-O surface is studied by a scanning tunneling microscope (STM) with atomic resolution. Tunneling is accomplished for various states of the tungsten STM probe, which allows oxygen an...

Formation of two-dimensional ordered magnetic nanolattices in opal structures
A method of forming a two-dimensional ordered superlattice of magnetic nanoparticles in close-packed opal structures of silica (SiO2) spheres has been developed. Nickel nanopowder with an average particle size of...
