that all films were uniform with a smooth surface,while the energy-dispersive spectroscopy(EDS) analysis showed that there was a visible dependence on the Ga/P ratio in the deposition conditions and confirmed that a residual Ga metallic phase was presented in the surface of all the films.The Raman analysis showed the structural evolution of the GaP films was strongly dependent on the deposition......
Academy of Sciences摘 要:A new insight into the promotion action of Co2+on both particle and metal deposition in Ni-diamond composite electrodeposition system... benefits to the transportation of particles in solution towards cathode, but also shortens their residence time on cathodic surface. Meanwhile, entry of particles is also promoted. For metals deposition......
