Formation and rapid evolution of domain structure at phase transitions in slightly inhomogeneous ferroelectrics
A. M. Bratkovsky, A. P. Levanyuk
We present the first analytical study of stability loss and evolution of domain structure in inhomogeneous ferroelectric samples for exactly solvable model. The model assumes a sho…
Three-body scattering problem and two-electron tunneling in molecular wires
A. S. Alexandrov, A. M. Bratkovsky, P. E. Kornilovitch
We solve the Lippmann-Schwinger equation describing elastic scattering of preformed pairs (e.g. bipolarons) off a short-range scattering center and find the two-particle transmissi…
Angular dependence of novel magnetic quantum oscillations in a quasi-two-dimensional multiband Fermi liquid with impurities
A. M. Bratkovsky, A. S. Alexandrov
The semiclassical Lifshitz-Kosevich-type description is given for the angular dependence of quantum oscillations with combination frequencies in a multiband quasi-two-dimensional F…
Charge dynamics and metal-insulator transition in SiGd and SiY alloys
D. N. Basov, A. M. Bratkovsky, P. F. Henning +5
Carrier dynamics in amorphous a-SiRE (RE=Gd, Y) films has been studied in the doping regime close to the metal-insulator transition by means of infrared spectroscopy.…
Proper ferroelastic phase transitions in thin epitaxial films with symmetry-conserving and symmetry-breaking misfit strains
A. M. Bratkovsky, A. P. Levanyuk
We study how the ferroelastic domain structure sets in in an epitaxial film of a material with second order proper ferroelastic transition. The domain structures considered are sim…
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…
Orientational dependence of current through molecular films
P. E. Kornilovitch, A. M. Bratkovsky
We study the current through molecular films as a function of orientation of the molecules in the film with respect to electrodes. It may change by more than an order of magnitude,…
