Effect of nitrogen doping on the structure and optical properties of n-type hydrogenated amorphous silicon thin films Maoyang Wu 1, Wei Li2, a, Junwei Fu1, Yijiao Qiu1 and Yadong Jiang2 1School of Optoelectronic Information, University of Electronic Science and Technology of China(UESTC), Chengdu, 610054, China 2State Key Laboratory of Electronic Thin Films and Integrated Devices, University of Electronic Science and Technology of China(UESTC), Chengdu, 610054, China awli@uestc.edu.cn Keywords–n-type hydrogenated amorphous silicon thin films, nitrogen doping, composition, microstructure, optical property Abstract—Hydrogenated amorphous silicon (a-Si:H) thin films doped with both Phosphor and Nitrogen are deposited by ratio frequency plasma enhanced chemical vapor deposition (PECVD).
However, exposure of intrinsic or lightly doped a-Si:H films to band-gap light causes degradation in the electronic properties, called the Staebler–Wronski effect [4–6], which has been proven to be an obstacle to the widespread application of this material in these fields.

Diffusion Measurements in Chromium-Manganese Steels by means of Multiple Radiotracer Test Joanna Dudała 1,a, Jolanta Gilewicz-Wolter1,b, Zdzisław Stęgowski1,c 1 Faculty of Physics and Applied Computer Science, AGH University of Science and Technology, Al.
Corrosion of metals and metallic alloys in such gases, at elevated temperatures, particularly in atmospheres containing sulfur and oxygen causes a significant degradation of metallic materials in industrial installations and is therefore of considerable interest.
Selection of the metallic materials used in modern industrial technologies is determined for the conditions in which they are supposed to work.
The absorption of the radiation in the sample material can be omitted considering the fact that all used isotopes are γ - emitters of high energy of the radiation.

Material life span significantly decreased and increased danger [7, 8] when fatigue occurred in structural material using fluids with a high temperature, pressure, and chemical reaction, such as steam generator tubes applied in a nuclear power plant.
Materials and Experimental Procedure The INCOLOY 800 applied in this study was a Ni-Fe-Cr alloy used as a steam generator tube.
The INCOLOY 800 was considered as excellent a material in ductility as the INCONEL alloys.
Acknowledges This study was supported by Korea Institute of Science & Technology Evaluation and Planning (KISTEP) and Ministry of Science & Technology (MOST), Korean government, through its National Nuclear Technology Program.
