Smearing of phase transition due to surface effect in ferroelectric nanostructures
A. M. Bratkovsky, A. P. Levanyuk
The boundary conditions, customarily used in the Landau-type approach to ferroelectric thin films and nanostructures, have to be modified to take into account that a surface of a f…
Vortex rectification effects in plain superconducting films
F. G. Aliev, A. P. Levanyuk, R. Villar +2
Superconducting films in perpendicular magnetic field are found to rectify alternating currents. The effect has been observed both in plain and nanostructured superconducting films…
On phase transitions in Pb/Ge(111) and Sn/Ge(111)
A. Cano, A. P. Levanyuk
The present communication is a critical examination of two points relevant to the surface phase transitions of Pb and Sn overlayers on Ge(111). One is connected with the reading of…
Rigidity of the elastic domain structure near the boundary of its existence in thin epitaxial films
A. M. Bratkovsky, A. P. Levanyuk
We consider an interesting and practically important case of elastic domain structure, which is the analogue of c/a domain pattern with 90 walls in perovskites, and is solv…
