Instability of Kinetic Roughening in Sputter-Deposition Growth of Pt on Glass

Abstract

Using scanning tunneling microscopy, we have studied the kinetic roughening in the growth of Pt sputter deposited on glass at room temperature for a film thickness range of 15–140 nm. The growth exhibits an irregularly growing mound morphology and shows an instability with anomalous scaling behavior characterized by the √ ln ( t ) dependence of the local slope, where t is the growth time, and also by the roughness exponent α ≃ 0.9 and interface growth exponent β ≃ 0.26 . These characteristics clearly indicate that the growth is consistent with a statistical model of linear diffusion dynamics.
