Research Abstract |
Ni clusters, particles and thin films grown on SrTiO3 substrates were studied by ultrahigh vacuum transmission electron microscopy and scanning tunneling microscopy combined system. Their morphologies, structures, interface structures, and electric structures were observed under varied environments. It was found out that their morphologies, interface structures and electric structure change depending on their sizes. Also, their morphologies and structures change by oxygen annealing, but they can be retrieved by vacuum annealing. Field induced diffusion of Ni atoms was also observed by applying voltages in some cases.
