Advanced methods in Glancing Angle Deposition to control thin film morphology, microstructure and textureDownload
Structuring of material on the nanoscale is enabling new functional materials and improving existing technologies. Glancing angle deposition (GLAD) is a physical vapor deposition technique that enables thin film fabrication with engineered columnar structures on the (10 to 100) nm scales. In this...
The glancing angle deposition (GLAD) technique is now used by over one hundred research groups, each requiring a fundamental understanding of and new techniques for modulating the properties of GLAD in order to optimize their results. In this thesis, the structural characteristics of...
This dissertation describes the use of a novel Pt deposition to prepare nickel- and carbon-supported platinum catalysts. The deposition is referred to herein as the platinum counter electrode deposition. The source of platinum is the sacrificial dissolution of a blacked platinum counter electrode...
This thesis investigates technologies directed towards developing photonic crystal display devices. A switching technology based on dye electrophoretic motion within a 1D porous photonic crystal was developed. Dissociated absorbing dye species were moved through the assembled device and...
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...
Sensor technologies profoundly impact all aspects of our everyday lives. Advances have led to smaller devices, faster response times, reduced costs, higher specificity and sensitivity, and even new sensing technologies. Surface acoustic wave (SAW) technology, which has been around for many...
This thesis presents a theoretical study of columnar films, fabricated by glancing angle deposition (GLAD), as photonic bandgap structures and metamaterials with predictable dielectric and magnetic response. Glancing angle deposition (GLAD) employs extremely oblique vapour incidence and...
Advanced optical technologies profoundly impact countless aspects of modern life. At the heart of these technologies is the manipulation of light using optical materials. Currently, optical technologies are created using naturally occurring materials. However, a new and exciting approach is to...
In this thesis, a new technique named vapour-liquid-solid glancing angle deposition (VLS-GLAD) will be used to enhance structural control over branched nanowire (NW) arrays. NWs are 1D crystals that have been extensively applied in sensors, photovoltaic devices, and transistors. The functional...
Fundamentals of Film Growth by Glancing Angle Deposition for Inorganic and Inorganic/Liquid Crystal Hybrid Optical SystemsDownload
This thesis investigates two facets of thin film growth via glancing angle deposition. The first half of the work focuses on the fundamentals of film growth with a focus on uniformity and optical design. This portion of the thesis addresses important engineering questions that are relevant to...
