MONTE Carlo method
Abstract

This work aims at analyzing the scaling behavior and develop correlations during surface growing for different germination lengths. The surface growing by random deposition is simulated using a kinetic Monte Carlo approach, by considering different germination lengths. Different surface descriptors are extracted, among them the roughness and the correlation. The former allows extracting the scaling behavior, while the latter proves the existence of correlations independent of the system size but dependent on the germination length. Moreover, as in the case of random deposition with a null germination length, the growing roughness never saturates. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Glancing angle deposition (GLAD) is a thin film fabrication technique capable of creating arrays of nanocolumns from numerous materials. Optimizing these films for applications requires an understanding of their growth, prompting research into the columns’ growth scaling behaviour. Columns are generally represented with a power law, capturing broadening in an exponent p. Existing literature measurements of p are inconsistent and difficult to repeat, in part due to complex branching in many GLAD ?lms and subjectivity in some existing techniques. This thesis describes a new method of studying growth scaling by disassembling films into a solvent and dispersing them across a substrate, facilitating automated measurement from top-down scanning electron microscopy. Minimizing the uncertainty and subjectivity introduced by branching, optimized implementations may permit fully automated high-throughput film characterization. Initial results track the influence of deposition rotation on broadening, presenting the first quantitative trend and potentially improving future nanostructure morphology control.
