Competing effects of Si and Mg doping on native point defects in yttrium aluminum garnet
L. Yu. Kravchenko, M. Yu. Vovsianiker, M. Y. Vovsianiker +1
We investigate how Si and Mg doping affect native point defects in yttrium aluminum garnet (YAG) by combining first-principles calculations with a thermodynamic model of defect equ…
Control of charge state of dopants in insulating crystals: Case study of Ti-doped sapphire
L. Yu. Kravchenko, D. V. Fil
We study mechanisms of control of charge state and concentration of different point defects in doped insulating crystals. The approach is based on the density functional theory cal…
Defect complexes in Ti-doped sapphire: A first principles study
L. Yu. Kravchenko, D. V. Fil
First-principles calculations have been performed to study the formation of defect complexes in Ti doped alpha-Al2O3 crystals. The formation energies of isolated Ti3+ and Ti4+ defe…
Superconductivity of electron-hole pairs in a bilayer graphene system in a quantizing magnetic field
D. V. Fil, L. Yu. Kravchenko
The state with a spontaneous interlayer phase coherence in a graphene based bilayer quantum Hall system is studied. This state can be considered as a gas of superfluid electron-hol…
Superfluid state of magnetoexcitons in double layer graphene structures
D. V. Fil, L. Yu. Kravchenko
The possibility of realization of a superfluid state of bound electron-hole pairs (magnetoexcitons) with spatially separated components in a graphene double layer structure (two gr…
Stationary waves in a supersonic flow of a two-component Bose gas
L. Yu. Kravchenko, D. V. Fil
A stationary wave pattern occurring in a flow of a two-component Bose-Einstein condensate past an obstacle is studied. We consider the general case of unequal velocities of two sup…
