Opis:: The aim of this paper is the study of porous Si prepared by preferential anodic dissolution in concentrated HF acid solutions. Porous silicon layers exhibited extremely efficient luminescence in the 700-900 nm range at room temperature. Basic characteristics of this luminescence strongly suggest the intrinsic origin of the process, directly related to quantum confinement. The additional transmission-electron-microscopy and electron-diffraction studies - were performed to support hypothesis that luminescence originates from silicon nanostructures.

Opis:: Al$\text{}_{0.3}$Ga$\text{}_{0.7}$As layers were grown by molecular beam epitaxy using substrate temperature 200-300°C, tetrameric As and two values of As/Ga+Al flux ratio i.e. 3 or 8. The post-growth annealing was performed in situ at 600°C for 20 min under As-overpressure. The samples were characterised by reflection high-energy electron diffraction, transmission electron microscope and room-temperature I-V measurements of n$\text{}^{+}$/LT grown layer /n$\text{}^{+}$ resistors. The resistivity and trap-filled limited voltage have been determined. The best layers exhibited ρ of the order of 10$\text{}^{9}$ Ω cm, were monocrystalline, uniformly precipitated and without dislocations.

Opis:: We report on photoreflectance investigations of strained-layer In$\text{}_{0.2}$Ga$\text{}_{0.8}$As/GaAs/Al$\text{}_{0.3}$Ga$\text{}_{0.7}$As single quantum well laser structures grown by molecular beam epitaxy. All the observed photoreflectance spectral features were assigned to the e-hh transitions with Δn=0. The transition energies were determined and compared to their values calculated within the envelope function approximation. Assuming that one third of the total strain in the central In$\text{}_{0.2}$Ga$\text{}_{0.8}$As layer is relaxed by biaxial deformation of surrounding thin GaAs layers, it is possible to explain reasonably the results of our photoreflectance experiment.

Opis:: The aim of the study is to analyze the hydraulic conditions of the existing sewage system and the sewage treatment plant in the commune of Mściwojów. This is in relation to the aspect of connecting new buildings, as a part of the investments in the pilot project VITAL LANDSCAPES no. 2CE164P3. The analysis led to the conclusion that an increased wastewater inflow from the new buildings is manageable. The current capacity of the sewage treatment plant will be increased by 3 to 5%, which will not affect the stability of the existing treatment process. The hydraulic analysis of the sewer network proved that the existing sewer collectors can handle the increased flow.
