Periodic polymers with increasing repetition unit: Energy structure and carrier transfer
K. Lambropoulos, C. Vantaraki, P. Bilia +2
We study the energy structure and the transfer of an extra electron or hole along periodic polymers made of monomers, with a repetition unit made of monomers, using a Tight…
Reducing influence of antiferromagnetic interactions on ferromagnetic properties of p-(Cd,Mn)Te quantum wells
C. Simserides, A. Lipinska, K. N. Trohidou +1
In order to explain the absence of hysteresis in ferromagnetic p-type (Cd,Mn)Te quantum wells (QWs), spin dynamics was previously investigated by Monte Carlo simulations combining…
Theory of ferromagnetism driven by superexchange in dilute magnetic semiconductors
C. Simserides, J. A. Majewski, K. N. Trohidou +1
Magnetic properties of GaMnN are studied theoretically by employing a tight binding approach to determine exchange integrals characterizing the coupling betwee…
Phase diagram and critical behavior of the random ferromagnet
S. Stefanowicz, G. Kunert, C. Simserides +11
Molecular beam epitaxy has been employed to obtain Ga1-xMnxN films with x up to 10% and Curie temperatures T_C up to 13 K. The magnitudes of T_C and their dependence on x, T_C(x) ~…
Density of states and extent of wave function: two crucial factors for small polaron hopping conductivity in 1D
Margarita Dimakogianni, Constantinos Simserides, Georgios P. Triberis
We introduce a theoretical model to scrutinize the conductivity of small polarons in one-dimensional disordered systems, focusing on two crucial --as will be demonstrated-- factors…
Origin of low-temperature magnetic ordering in Ga1-xMnxN
M. Sawicki, T. Devillers, S. Gałȩski +9
By employing highly sensitive millikelvin SQUID magnetometry, the magnitude of the Curie temperature as a function of the Mn concentration x is determined for thoroughly characteri…
Ferromagnetic properties of p-(Cd,Mn)Te quantum wells: Interpretation of magneto-optical measurements by Monte Carlo simulations
A. Lipinska, C. Simserides, K. N. Trohidou +4
In order to single out dominant phenomena that account for carrier-controlled magnetism in p-(Cd,Mn)Te quantum wells we have carried out magneto-optical measurements and Monte Carl…
Density of states and electron concentration of double heterojunctions subjected to an in-plane magnetic field
C. Simserides
We calculate the electronic states of AlGaAs/GaAs/AlGaAs double heterojunctions subjected to a magnetic field parallel to the quasi two-dimensional electron…
Local absorption spectra of artificial atoms and molecules
C. Simserides, U. Hohenester, G. Goldoni +1
We investigate theoretically the spatial dependence of the linear absorption spectra of single and coupled semiconductor quantum dots, where the strong three-dimensional quantum co…
