Effects of annealing and substrate orientation on epitaxial growth of GaAs on Si
GaAs thin films grown on Si (100) and (111) substrates by metal-organic chemical vapor deposition were investigated by electron microscopy. It was found that the growth rate of the GaAs epitaxial laye...

Multiphase structure including the metallic glass matrix and the primary crystalline phase(s) was found in the Gd55Co15Al30−xGex (0<=x<=10) alloys. It was confirmed by x-ray diffraction and energy dispersive spectroscopy that the primary crystalline phase was Gd5Ge3 when x>=5. Based on these results, ternary bulk metallic glasses with composition of Gd52.5–53.8Co16.5–20.5Al25.7–31.0, which exhibit good glass forming ability and high thermal stability, were discovered. ©2009 American Institute of Physics
