Ga sublattice defects in (Ga,Mn)As: thermodynamical and kinetic trends.
We have used positron annihilation spectroscopy and infrared absorption measurements to study the Ga sublattice defects in epitaxial Ga(1-x)MnxAs with Mn content varying from 0% to 5%. We show that the Ga vacancy concentration decreases and As antisite concentration increases with increasing Mn content. This is in agreement with thermodynamical considerations for the electronic part of the form...
متن کاملRecent advances in parallel kinetic Monte Carlo: synchronous sublattice algorithm
Abstract. An efficient, semi-rigorous synchronous algorithm for parallel kinetic Monte Carlo simulations is presented. The accuracy and parallel efficiency are studied as a function of processor size, number of processors, and the ratio D/F of monomer hopping rate (D) to deposition rate (F ) for two different simple models of epitaxial growth. Since only local communication is required, the alg...
متن کاملDetermination of the local concentrations of Mn interstitials and antisite defects in GaMnAs.
We present a method for the determination of the local concentrations of interstitial and substitutional Mn atoms and As antisite defects in GaMnAs. The method relies on the sensitivity of the structure factors of weak reflections to the concentrations and locations of these minority constituents. High spatial resolution is obtained by combining structure factor measurement and x-ray analysis i...
متن کاملGaMnAs: Layers, Wires and Dots
Thin layers of GaMnAs ferromagnetic semiconductor grown by molecular beam epitaxy on GaAs(001) substrates were studied. To improve their magnetic properties the post-growth annealing procedures were applied, using the surface passivation layers of amorphous arsenic. This post-growth treatment effectively increases the ferromagnetic-to-paramagnetic phase transition temperature in GaMnAs, and pro...
متن کاملSemirigorous synchronous sublattice algorithm for parallel kinetic Monte Carlo simulations of thin film growth
The standard kinetic Monte Carlo algorithm is an extremely efficient method to carry out serial simulations of dynamical processes such as thin film growth. However, in some cases it is necessary to study systems over extended time and length scales, and therefore a parallel algorithm is desired. Here we describe an efficient, semirigorous synchronous sublattice algorithm for parallel kinetic M...
