Abstract

The morphology evolution of Ag nanoparticles (NPs) deposited by glancing angle deposition (GLAD) in a wide range of nominal deposition thickness d at room temperature has been investigated systematically. Nonspherical Ag NPs are formed with d < 500 nm, while vertical Ag-nanorod-like nanostructures are produced when d > 500 nm. Based on three-dimensional Monte Carlo simulations, such a morphological change can be attributed to the high mobility and re-emission of Ag atoms as well as the shadowing effect during the GLAD growth.
