The suitability for high voltage devices has been tested using an Al-implanted pin-diode structure.
Temperature dependent mole fractions x of growth relevant species (x>10 -7) were calculated by aid of the program "HSC Chemistry 4.1" of Outukumpu 1.
The averaged roughness of thick CW-layers was found to be larger than that of HW-layers by a factor of 10, which can cause technological problems, e.g. in structure reconciliation of mask alignment.
Concerning the crystal structure quality measured by XRD different epi-layers were grown on substrates of the same crystal to minimize the influence of a different substrate quality.
Al-implanted pin-diodes with an active area of 7 mm2 have been fabricated using the same technology for all tested structures.

In this work the investigation aims at synthesis of green Y4MgSi3O13 phosphors by a sol-gel process as well as studying their crystal structure and luminescence properties.
When the calcination temperature is above 1000˚C, the crystal structure may be destroyed, the particles after reuniting melt into a large particle, which leds phosphor luminescence intensity to decrease.
When calcined under 1000˚C, phosphor samples have the maximum diffraction intensity and better crystal structure.
Phosphor bulk structure do not changed obviously after Tb3+ and Ce3+ ions doped.

It is well known that the chilling tendency of cast irons determines their subsequent performance in diverse applications.Hence, considerable efforts [1-4] have been made in correlating the inoculation practice, the chemistry, the pouring temperature, etc. with the difference in the chilling tendency of cast iron.

Structure and Corrosion Behavior of Mg-Cu-Y-(Zn,Ni) Bulk Metallic Glasses Rafał Babilas1,a*, Katarzyna Cesarz-Andraczke1,b, Dorota Babilas2,c and Wojciech Simka2,d 1Institute of Engineering Materials and Biomaterials, Silesian University of Technology, Konarskiego 18a, 44-100 Gliwice, Poland 2Department of Inorganic, Analytical Chemistry and Electrochemistry, Silesian University of Technology, Krzywoustego 6, 44-100 Gliwice, Poland a*rafal.babilas@polsl.pl, bkatarzyna.cesarz@polsl.pl, cdorota.babilas@polsl.pl dwojciech.simka@polsl.pl Keywords: amorphous materials; bulk metallic glasses; magnesium alloy; corrosion resistance.
The structure analysis of the samples was carried out by the XRD and DSC methods.
Novel amorphous magnesium-based alloys exhibit good mechanical properties and significantly improved corrosion resistance by controlling the structure of Mg-based alloys.
Mg-based metallic glasses are characterised by single-phase amorphous structure and contain elements of higher electrochemical potential than magnesium.
The structure of the “as-cast” samples was tested by X-ray diffractometer (XRD) Seifert-FPM XRD 7 in reflection mode with Co Κα radiation.

In this work, the influence of the amount of F127 on the structure of Ti-OMCs was also investigated.
Ti-OMC-0.015-1 and Ti-OMC-0.015-0.5 show strip-like channels, which are typical images of 2-D hexagonal structure.
However, when F127 content is 0.3, TEM image of body-centered cubic structure is observed in Fig. 4 (c).
F127 contents can influence both regularity and symmetry structure of Ti-OMCs.

Surface morphology and elemental composition of the obtained hybrid polymer-oxide material are examined with an electron microscopy and X-ray micro-fluorescent microanalysis; its phase composition and its chemical bonds structure formation between metal oxide compounds and polymer macromolecules are determined by X-ray phase analysis and IR spectroscopy.
The latter may be caused by the opening of PVP polymer chains due to metal molecules or metal oxides incorporation into their structure [15].
