In this paper, we briefly report on a detailed investigation of the morphology of voids in the Fe-40 wt.%Ni alloy using the electron holography technique. By analyzing the phase shift across the voids, we could obtain visual information on their morp

The polarity of ZnO films grown on MgO∕c-Al2O3 templates are successfully controlled by only varying MgO buffer layer thickness. The crystal structure of the MgO buffer on c-Al2O3 is of wurtzite (WZ), when the MgO buffer thickness is less than 2.7n
