Book Description
Thin-films grown via glancing-angle deposition (GLAD) have interesting structural, mechanical, and optical properties and may be used for a variety of applications including sensors, optical filters, antireflection coatings, fuel cells, and magnetic data storage. However, due in part to the complexity of the resulting thin-film structures as well as to the large range of time- and length- scales, realistic simulations of the thin-film growth process for large deposition angles have in the past been difficult. As a result, typically only simulations of effective models of GLAD, or of more realistic models for smaller deposition angles, have been carried out. As a first step in understanding the dependence of the surface morphology and microstructure in GLAD on deposition parameters, here we present the results of large-scale MD simulations of Cu/Cu(100) growth for the case of large deposition angle. In particular, by taking advantage of the speed of recently developed graphical-processing-units (GPUs) we have carried out large-scale GPU-enhanced MD simulations of Cu/Cu(100) growth up to 20 monolayers (ML) for deposition angles (corresponding to the angle with respect to the substrate normal) ranging from 50o to 85o and for both random and fixed azimuthal angles. In general, we find good agreement with experiment results for the dependence of thin-film porosity on deposition angle and film-thickness. Results for the dependence of the surface roughness, lateral correlation length and microstructure (e.g. defect density, vacancy density, surface sites, and strain) on the deposition angle and film thickness are also presented.

Glancing Angle Deposition of Thin Films
Author: Matthew M. Hawkeye
Publisher: John Wiley & Sons
ISBN: 1118847334
Category : Technology & Engineering
Languages : en
Pages : 435
Book Description
This book provides a highly practical treatment of Glancing Angle Deposition (GLAD), a thin film fabrication technology optimized to produce precise nanostructures from a wide range of materials. GLAD provides an elegant method for fabricating arrays of nanoscale helices, chevrons, columns, and other porous thin film architectures using physical vapour deposition processes such as sputtering or evaporation. The book gathers existing procedures, methodologies, and experimental designs into a single, cohesive volume which will be useful both as a ready reference for those in the field and as a definitive guide for those entering it. It covers: Development and description of GLAD techniques for nanostructuring thin films Properties and characterization of nanohelices, nanoposts, and other porous films Design and engineering of optical GLAD films including fabrication and testing, and chiral films Post-deposition processing and integration to optimize film behaviour and structure Deposition systems and requirements for GLAD fabrication A patent survey, extensive relevant literature, and a survey of GLAD's wide range of material properties and diverse applications.
