Selenidation of epitaxial silicene on ZrB2

Applied Surface Science, 2018
The deposition of elemental Se on epitaxial silicene on ZrB2 thin films was investigated with synchrotron-based core-level photoelectron spectroscopy and low-energy electron diffraction. The deposition of Se at room temperature caused the appearance of Si 2p peaks with chemical shifts of n × 0.51 ± 0.04 eV (n = 1-4), suggesting the formation of SiSe2 ...

Effects of in-situ ZrB2 particle on grain refinement of ZrB2/AZ91D magnesium matrix composite

China Foundry, 2012
In-situ ZrB2/AZ91D magnesium matrix composite was successfully synthesized with Al/K2ZrF6+NH4BF4 by means of Direct Melt Reaction. The fabricated ZrB2 /AZ91D magnesium matrix composite through direct melt mixing method was investigated. Results from X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS) confirmed the existence of ZrB2 ...
