Opis:
Halogen transport method was applied to grow the crystals of solid solutions of ZnSe and transition metals at the temperature far below the melting point and phase transition temperature. The large crystals of ZnMnSe, ZnFeSe, ZnNiSe and ZnFeSSe were obtained. The technological parameters and shape of the quartz reactor were chosen for growth of a large crystal by self-nucleation; the transparent quartz furnace enabled the control of nucleation by visual observation. The parameters of crystal growth were determined. The crystal quality was estimated by X-ray diffraction method. The composition of crystals was determined by electron microprobe analysis and energy dispersive X-ray fluorescence analysis.

Opis:
The aim of the present paper is to study the possibility of application of the X-ray quasi-forbidden reflection method to the composition determination of the sphalerite-type Cd$\text{}_{1-x}$M$\text{}_{x}$Te = Mg, Zn, Mn) single crystals. The method is based on the property of quasi-forbidden reflections that their integral intensity is very sensitive to composition and weakly sensitive to crystal lattice defects. An example of application for a Cd$\text{}_{1-x}$Mn$\text{}_{x}$Te single crystal is presented.

Opis:
The Si(111) wafer cut from a bulk single crystal obtained by the Czochralski method was implanted with 5×10$\text{}^{16}$ I cm$\text{}^{-2}$ of As ions of energy 80 keV. The dose applied was chosen above the amorphization limit of the silicon substrate. Two samples, implanted and a reference, were studied by grazing incidence X-ray reflectometry and X-ray diffraction methods using a high resolution Philips MRD system equipped with a Cu source and a channel-cut monochromator. The obtained spectra were compared with distributions of ion range and defect production calculated with TRIM program [1], as well as with theoretical models of reflectivity [2, 3]. The results of grazing incidence X-ray reflectometry reflectivity of the implanted sample show well-pronounced oscillations, which can be associated with a layer about 50 nm thick, approximately comparable to the thickness of the defected layer estimated from the TRIM method. Theoretical calculations of reflectivity clearly indicate an occurrence of a Si layer of electron density lower about 10-15% comparing to the unimplanted Si sample. This can be due to the vacancy production during ion implantation. A comparison of the spectra with a density distribution profile concluded from the TRIM calculations shows large discrepancies. The results indicate the applicability of grazing incidence X-ray reflectometry method in a study of amorphization processes in implanted layers.

Opis:
The paper shows an influence of doping on lattice constant of a semiconductor. Three effects are discussed: (i) "size" effect caused by a different ionic radii of dopant and host atoms, (ii) lattice expansion by free electrons proportionally to the deformation potential of the conduction-band minimum occupied by this charge, (iii) different thermal expansion of the undoped and doped samples. The experiments have been performed by using the high resolution X-ray diffraction at 77-770 K on AlGaAs:Te and GaAs:Si.

Opis:
Experimental evidence for unidirectional microcracking in semi-bulk AlGaAs layers grown on (001) GaAs substrates is presented. The asymmetrical microcracking leads to anisotropic lattice misfit relaxation in the AlGaAs/GaAs structure and is explained in terms of higher mobility of [-110]-oriented α-type dislocations than that of β-type dislocations oriented in [110] direction.

Opis:
The changes of defect structure of GaP:N epitaxial layers subjected to hydrostatic pressures up to 1.8 GPa are investigated by X-ray diffraction and photoluminescence. The observed changes are more pronounced at higher pressures and depend on the nitrogen concentration, c$\text{}_{N}$, and on initial defect structure. Especially complex hydrostatic pressure induced properties are observed for the sample with c$\text{}_{N}$ > 10$\text{}^{20}$ at. cm$\text{}^{-3}$. The model explaining the hydrostatic pressure induced defect structure changes is proposed.

Opis:
AlGaAs layers grown by molecular beam epitaxy on GaAs substrates were investigated before and after high hydrostatic pressure (1.2 GPa) at high temperature (770 K) treatment. In order to study the influence of high pressure - high temperature treatment on the physical properties of the AlGaAs layers, X-ray, electron transport and Raman scattering measurements were performed at room temperature. The observed changes in the lattice parameter, Raman spectra and free-carrier concentration were related to the strain relaxation and explained by the creation of misfit dislocations and other extended defects which were visible on the synchrotron X-ray topographs after high pressure - high temperature treatment.

Effect of hydrostatic pressure up to 1.2 GPa on oxygen-implanted silicon, Si:O (O$\text{}^{+}$ dose, D, within the 6×10$\text{}^{17}$-2×10$\text{}^{18}$ cm$\text{}^{-2}$ range), treated at 1230-1570 K, was investigated by X-ray, transmission electron microscopy and photoluminescence methods. The pressure treatment affects oxygen precipitation and defect creation, especially in low oxygen dose implanted Si:O (D=6×10$\text{}^{17}$ cm$\text{}^{-2}$). Such investigation helps in understanding the stress related phenomena in Si wafers with buried insulating layer.

An influence of HP-HT treatment on the properties of the AlGaAs/GaAs system was studied by lattice parameter measurements using the high resolution diffractometer and by X-ray topography. Observed changes in the lattice parameter of the AlGaAs layers after HP-HT treatment are related to the strain relaxation and explained by the creation of misfit dislocations and other extended defects which are visible on the topographs.

Hydrostatic pressure promotes oxygen precipitation from oversaturated Si-O solid solution and the creation of structural defects.

Opis:
Phonon excitations in (CdTe)$\text{}_{12}$/(MnTe)$\text{}_{n}$ (100) superlattices (n=2, 4, 8) were investigated at 295 K and 25 K with the use of Raman scattering. From the "folded" phonon frequencies the elastic constant c$\text{}_{11}$ value for MnTe was estimated. The strain arising from lattice mismatch (determined by X-ray diffraction) results in shifts of MnTe and CdTe "confined" LO phonon frequencies. For the precise determination of LO phonon dispersions an additional shift due to Mn diffusion at the CdTe/MnTe interface should be taken into account.

Opis:
Sensitivity of X-ray integral reflectivity of GaAs single crystal to a degree of structure distortions was established to grow considerably in the Bragg diffraction case when the characteristic AgK_{α$\text{}_{1}}$ line is changed for more hard white radiation. In effect, the absorption length essentially exceeds the extinction length what results in enhancement of incoherent scattering. Measurements of X-ray integral reflectivity coordinate dependence by single crystal spectrometer permitted to determine the mean level of crystal lattice distortion as well as the degree of structure homogeneity of a sample with dislocations. The Debye-Waller static factor value was estimated from X-ray integral reflectivity magnitudes for the 800 reflection of white radiation.
