Opis:: Conductivity and structure of materials belonging to pseudo-binominal group $(AgI-Ag_2MoO_4)$ were investigated. Structure was investigated by X-ray and scanning electron microscopy techniques. It was found that described materials present a variety of internal structures. This type of structures affects conductivity at room temperature, so there is correspondence between conductivity and structure.

Opis:: In this paper we investigate electron emission/capture from/to the DX state of indium in CdTe by means of high pressure freeze-out cycle and steady-state photo-conductivity experiments. The results indicate that the DX state is occupied by two electrons. A comparison with deep level transient spectroscopy data shows that two-electron emission occurs at low temperatures, while one-electron emission takes place at high temperatures.

Opis:: The present status of the LuAlO$\text{}_{3}$:Ce scintillator is reviewed. Scintillation mechanism of this material is based on capture by Ce$\text{}^{3+}$ of holes and then electrons from their respective bands. Results of spectroscopic and thermoluminescence experiments are presented to support this model.

Opis:: Room temperature, continuous wave operation of InGaN multi-quantum wells laser diodes made by rf plasma assisted molecular beam epitaxy at 411 nm wavelength is demonstrated. The threshold current density and voltage were 4.2 kA/cm$\text{}^{2}$ and 5.3 V, respectively. High optical power output of 60 mW was achieved. The lifetime of these laser diodes exceeds 5 h with 2 mW of optical output power. The laser diodes are fabricated on low dislocation density bulk GaN substrates, at growth conditions which resembles liquid phase epitaxy. We demonstrate that relatively low growth temperatures (600-700°C) pose no intrinsic limitations for fabrication of nitride optoelectronic components by plasma assisted molecular beam epitaxy.
