Multiband Electronic Structure of Magnetic Quantum Dots: Numerical Studies
D. Rederth, R. Oszwaldowski, A. G. Petukhov +1
Semiconductor quantum dots (QDs) doped with magnetic impurities have been a focus of continuous research for a couple of decades. A significant effort has been devoted to studies o…
Fermi level position, Coulomb gap, and Dresselhaus splitting in (Ga,Mn)As
S. Souma, L. Chen, R. Oszwaldowski +5
Carrier-induced nature of ferromagnetism in a ferromagnetic semiconductor, (Ga,Mn)As, offers a great opportunity to observe novel spin-related phenomena as well as to demonstrate n…
Spin Modulation in Semiconductor Lasers
Jeongsu Lee, William Falls, Rafal Oszwaldowski +1
We provide an analytic study of the dynamics of semiconductor lasers with injection (pump) of spin-polarized electrons, previously considered in the steady-state regime. Using comp…
Dipole formation at metal/PTCDA interfaces: Role of the Charge Neutrality Level
H. Vazquez, R. Oszwaldowski, P. Pou +4
The formation of a metal/PTCDA (3, 4, 9, 10-perylenetetracarboxylic dianhydride) interface barrier is analyzed using weak-chemisorption theory. The electronic structure of the unco…
Barrier formation at metal/organic interfaces: dipole formation and the Charge Neutrality Level
H. Vazquez, F. Flores, R. Oszwaldowski +3
The barrier formation for metal/organic semiconductor interfaces is analyzed within the Induced Density of Interface States (IDIS) model. Using weak chemisorption theory, we calcul…
