Nettet1. des. 1990 · More than 20 years ago Movchan and Demchishin published their structure zone model (SZM) of thin film morphology as a function of a single macroscopic parameter, the normalized substrate temperature. In all its simplicity, this model already reflects many experimental observations of thin film growth with surprising accuracy.

Nettet15. nov. 2024 · A metal film deposited on a substrate with a temperature gradient has three characteristic structure zones with the boundary temperatures Ts / Tm = 0.3 and Ts / Tm = 0.5, where Ts is the substrate temperature and Tm is the metal melting point (in kelvin) (Movchan &amp; Demchishin, 1969; Higo et al., 2006 ). NettetThe film morphology does not fit the structure zone model of Movchan, Demchishin and Thornton. Langevin molecular dynamics simulations give the following physical picture: a tiny, very high temperature spot is formed at each impact. This anneals the area around the impact zone and gives rise to near epitaxial growth.
