A completely dry technique (VPD) for the preparation of a metal cluster onto a polymer surface or between two polymer layers opens up very good possibilities to control the two dimensional dispersion of the metal clusters and their size during variation of the deposition parameters or the polymer surface treatment. The kinetics of heterogenous nucleation and the growth of nano-size metal clusters...
Undoped ZnO thin films were deposited on unheated sapphire and glass substrates under concurrent glancing-angle Ar + ion bombardment. Surface roughness decreased from 18 to 3.5 nm in films grown on glass, and from 11 to 0.5 nm on sapphire, as the ion-to-neutral atom ratio increased from 0 to 0.25. Film microstructure observations by cross-sectional electron microscopy indicated increased film...
