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…

Spin extraction from a non-magnetic semiconductor
A. M. Bratkovsky, V. V. Osipov
New efficient mechanism of obtaining spin polarization in_nonmagnetic_ semiconductors at arbitrary temperutures is described. The effect appears during tunneling of electrons from…
