Findings in the Area of Physics Research Reported from National Technical University (Structural and phase transformations in C/Si multilayers during annealing)

By a News Reporter-Staff News Editor at Physics Week -- Fresh data on Physics Research are presented in a new report. According to news reporting out of Kharkov, Ukraine, by VerticalNews editors, research stated, "The structural evolution of a C/Si periodical multilayers is studied by small-angle X-ray diffraction and cross-section transmission electron microscopy. Mixed zones 0.6-0.65 nm thick with different densities are detected at the C/Si and Si/C interfaces in the initial state."

Our news journalists obtained a quote from the research from National Technical University, "The effect of annealing on the thickness, the density, and the phase composition of the layers and the mixed zones is investigated in the temperature range 300-1050A degrees C. Two stages of changing the multilayer composition period upon heating are found. The period increases as the temperature increases up to 700A degrees C and then decreases."

According to the news editors, the research concluded: "The fracture of the composition begins in the silicon layers, where pores and cubic 3C-SiC nanocrystals form at 900A degrees C. The fracture of the layered structure of the composition is completed at T> 1000A degrees C."
