Influence of interface structure on electronic properties and Schottky barriers in Fe/GaAs magnetic junctions

D. O. Demchenko, Amy Y. Liu

The electronic and magnetic properties of Fe/GaAs(001) magnetic junctions are investigated using first-principles density-functional calculations. Abrupt and intermixed interfaces…

Optical transitions and nature of Stokes shift in spherical CdS quantum dots

D. O. Demchenko, Lin-Wang Wang

We study the structure of the energy spectra along with the character of the states participating in optical transitions in colloidal CdS quantum dots (QDs) using the {\sl ab initi…

Effect of Particle-Hole Asymmetry on the Mott-Hubbard Metal-Insulator Transition

D. O. Demchenko, A. V. Joura, J. K. Freericks

The Mott-Hubbard metal-insulator transition is one of the most important problems in correlated electron systems. In the past decade, much progress has been made on examining a par…

Electronic Structure of Transition-Metal Dicyanamides Me[N(CN)] (Me = Mn, Fe, Co, Ni, Cu)

D. O. Demchenko, Amy Y. Liu, E. Z. Kurmaev +7

The electronic structure of Me[N(CN)] (Me=Mn, Fe, Co, Ni, Cu) molecular magnets has been investigated using x-ray emission spectroscopy (XES) and x-ray photoelectron spectr…

Thermal transport in the Falicov-Kimball model on a Bethe lattice

A. V. Joura, D. O. Demchenko, J. K. Freericks

We calculate thermal transport in the Falicov-Kimball model on an infinite-coordination-number Bethe lattice. We perform numerical calculations of the thermoelectric characteristic…

Electron Spin Polarization in Resonant Interband Tunneling Devices

A. G. Petukhov, D. O. Demchenko, A. N. Chantis

We study spin-dependent interband resonant tunneling in double-barrier InAs/AlSb/ GaMnSb heterostructures. We demonstrate that these structures can be used as spin filters utilizin…
