WebDec 17, 2024 · We report on the dewetting process, in a high vacuum environment, of amorphous Ge thin films on SiO 2 /Si (001). A detailed insight of the dewetting is obtained … WebThin metal films deposited on ceramic substrates tend to undergo dewetting (agglomeration) at elevated temperatures even in the solid state. We characterized the dewetting of 40 nm thick Ni films on sapphire in the temperatures range of 700–900 °C and explored the effect of a minor (below 1 at.%) Au doping on the dewetting kinetics.

WebThe dynamics of solid state dewetting phenomena of a 50nm thick, mazed bicrystalline Al film on single crystalline α-Al2O3(sapphire) substrates was studied in-situ using an environmental scanning electron microscope (ESEM). The bicrystalline Al thin films served as a model system where the influence of grain boundaries and texture effects are well … iphone the missing manual edition

WebThe Ni-Fe particles with Fe concentration of 0-50 at.% were synthesized by solid-state dewetting of Ni-Fe bilayer thin films deposited on a sapphire substrate. Ni-27Fe and Ni-50Fe particles exhibited a bimodal size distribution with small (111) and large (100) oriented particles. The solid solution softening was observed in all particles. WebJan 29, 2024 · Core(Fe)-shell(Au) nanoparticles are obtained by solid-state dewetting of thin Fe/Au bilayer films deposited on a sapphire substrate. The core-shell morphology is achieved by employing the equilibrium segregation phenomenon, where Au atoms form a homogeneous thin shell on the surfaces of an Fe nanoparticle and at its interface with the … WebThin films will spontaneously dewet to form islands when heated to temperatures at which the mobility of the constituent atoms is sufficiently high.
