Non-perturbative macroscopic theory of interfaces with discontinuous dielectric constant
Y. M. Beltukov, A. V. Rodina, A. Alekseev +1
Discontinuity of dielectric constants at the interface is a common feature of all nanostructures and semiconductor heterostructures. Near such interfaces, a charged particle create…
Theory of acoustic-phonon involved exciton spin flip in perovskite semiconductors
A. V. Rodina, E. L. Ivchenko
We present a theory of the acoustic phonon assisted spin-flip Raman scattering (SFRS), or resonant photoluminescence with the spin flip of a photoexcited exciton localized in a bul…
Theory of resonant Raman scattering due to spin-flips of resident charge carries and excitons in perovskite semiconductors
A. V. Rodina, E. L. Ivchenko
We have developed a theory of Raman scattering with single and double spin flips of localized resident electrons and holes as well as nonequilibrium localized excitons in semicondu…
Third harmonic generation on exciton-polaritons in bulk semiconductors subject to a magnetic field
W. Warkentin, J. Mund, D. R. Yakovlev +7
We report on a comprehensive experimental and theoretical study of optical third harmonic generation (THG) on the exciton-polariton resonances in the zinc-blende semiconductors GaA…
Exciton spectroscopy of semiconductors by the method of optical harmonics generation
D. R. Yakovlev, V. V. Pavlov, A. V. Rodina +4
Nonlinear optical phenomena are widely used for the study of semiconductor materials. The paper presents an overview of experimental and theoretical studies of excitons by the meth…
Effects of strain on the valence band structure and exciton-polariton energies in ZnO
Markus R. Wagner, Gordon Callsen, Juan S. Reparaz +6
The uniaxial stress dependence of the band structure and the exciton-polariton transitions in wurtzite ZnO is thoroughly studied using modern first-principles calculations based on…
Fine structure of the band edge excitons and trions in CdSe/CdS core/shell nanocrystals
A. Shabaev, A. V. Rodina, Al. L. Efros
We present a theoretical description of excitons and positively and negatively charged trions in "giant" CdSe/CdS core-shell nanocrystals (NCs). The developed theory provides the p…
Intrinsic electric polarization in spin-orbit coupled semiconductor heterostructures
A. V. Rodina, A. Yu. Alekseev
We present Maxwell equations with source terms for the electromagnetic field interacting with a moving electron in a spin-orbit coupled semiconductor heterostructure. We start with…
Least action principle for envelope functions in abrupt heterostructures
A. V. Rodina, A. Yu. Alekseev
We apply the envelope function approach to abrupt heterostructures starting with the least action principle for the microscopic wave function. The interface is treated nonperturbat…
Magneto-Optical Properties of Bound Excitons in ZnO
A. V. Rodina, M. Strassburg, M. Dworzak +6
We present results of magneto-optical measurements and theoretical analysis of shallow bound exciton complexes in bulk ZnO. Polarization and angular dependencies of magneto-photolu…

A. V. Rodina, A. Yu. Alekseev, Al. L. Efros +2
We have derived general boundary conditions (BC) for the multiband envelope functions (which do not contain spurious solutions) in semiconductor heterostructures with abrupt hetero…
