Tytuł:: One and Two Phonon Assisted Transitions between Exciton Spin States in a Quantum Dot

Opis:: Exciton spin decay is studied in a self-assembled InAs/GaAs quantum dot. The spin relaxation results from an interplay of two factors: the Bir-Pikus Hamiltonian and the short-range exchange interaction, leading to one and two phonon assisted transitions. We establish a hierarchy between the resulting transition rates and show the dominating role of transverse phonons for all the transitions.

Opis:: The effect of laser surface treatment on structure and mechanical properties aluminium Alloy enac-AlMg9 In this work, the influence of a high power diode laser surface treatment on the structure and properties of aluminium alloy has been determined. The aim of this study was to improve the mechanical and tribological properties of the surface layer of the aluminium alloy by simultaneously melting and feeding tungsten carbide particles into the molten pool. During the process was used high-power diode laser HPDL. In order to remelt the aluminium alloy surface the HPDL laser of 1.8, 2.0 and 2.2 kW laser beam power has been used. The linear laser scan rate of the beam was set 0.5 em's. In order to protect the liquid metal during laser treatment was used argon. As a base material was used aluminium alloy ENAC -AlMg9. To improve the surface mechanical and wear properties of the applied aluminium alloy was used biphasic tungsten carbide WC/W₂C. The size of alloying powder was in the range 110-210 μm. The ceramic powder was introduced in the remelting zone by a gravity feeder at a constant rate of 8 g/m.
