Thermodynamics of Electromechanically-Coupled Mixed Ionic-Electronic Conductors: Deformation potential, Vegard strains and Flexoelectric effect
A. N. Morozovska, E. A. Eliseev, A. K. Tagantsev +3
Strong coupling among external voltage, electrochemical potentials, concentrations of electronic and ionic species, and strains is a ubiquitous feature of solid state mixed ionic-e…
Anion vacancy driven magnetism in incipient ferroelectric SrTiO3 and KTaO3 nanoparticles
E. A. Eliseev, A. N. Morozovska, M. D. Glinchuk +1
Based on our analytical results [http://arxiv.org/abs/1006.3670], we predict that undoped nanoparticles (size <10-100nm) of incipient ferroelectrics without any magnetic ions can b…
Defect driven ferroelectricity and magnetism in nanocrystalline KTaO3
I. S. Golovina, S. P. Kolesnik, V. Bryksa +6
Nominally pure nanocrystalline KTaO3 was thoroughly investigated by micro-Raman and magnetic resonance spectroscopic techniques. In all samples the defect driven ferroelectricity a…
Depletion of carriers and negative differential conductivity in an intrinsic graphene under a dc electric field
P. N. Romanets, F. T. Vasko
The heating of carriers in an intrinsic graphene under an abrupt switching off a dc electric field is examined taking into account both the energy relaxation via acoustic and optic…
Landau-Ginzburg-Devonshire theory for electromechanical hysteresis loop formation in piezoresponse force microscopy of thin films
A. N. Morozovska, E. A. Eliseev, S. L. Bravina +1
Electromechanical hysteresis loop formation in piezoresponse force microscopy of thin ferroelectric films is studied with special emphasis on the effects of tip size and film thick…
Carrier heating and high-order harmonics generation in doped graphene by a strong ac electric field
F. T. Vasko
The nonlinear response of electrons (holes) in doped graphene on ac pumping is considered theoretically for the frequency region above the energy relaxation rate but below the mome…
