Bartosz Jabłoński,Marek Kulbacki electronics. The recent first realization of an InGaN multi-quantum-well laser diode is a great progress in the development of ultraviolet optoelectronic devices. In spite of this and other successes, there is a continuing discussion about the processes responsible for the laser emission. The prese

Therefore, SiC is piezoelectric and shows a strong ‘Reststrahl’ absorption which allows the investigation of optical transitions due to impurities (vibrational and electronic tran

Mateusz Modrzejewski,Przemysław Rokita results demonstrate that similar SiC growth mechanisms act in all vapour phase epitaxial techniques. They also show that the control of the Si/C ratio and the super-saturation (.) is essential for the growth mode and the kind of polytype grown. Low temperature (.<1200 °C) deposition on on-axis SiC

The main factors influencing chemical bonding will be discussed, namely the atomic density, the annealing time for structural relaxation and the incorporated hydrogen fraction. By comparing the π-orbital characteristics, such as . gaps and defe

We identify the quantum numbers of the states by measuring the magnetic field dependence. We find that transitions in the ground states originate from crossings between s
