Phase stability in ti/bcc multilayered thin films
Materials structures with large surface area-to-volume ratios can exhibit size dependent physical and chemical properties that are different than their bulk form. These changes are often related to the material adopting a different crystallographic phase. Often these phase transformations are …

Low-Temperature Chemical Vapor Deposition of Ruthenium and Manganese Nitride Thin Films
Materials and thin film processing development has been and remains key to continuing to make ever smaller, or miniaturized, microelectronic devices. In order to continue miniaturization, conformal, low-temperature deposition of new electronic materials is needed. Two techniques capable of …

The growth and characterisation of ordered arrays of zinc oxide nanostructures and optical studies of defects in zinc oxide
In this work the growth of c-axis aligned zinc oxide nanorods on non-epitaxially matched substrates is examined. Nanorod arrays were deposited on silicon by seeding and chemical bath deposition (CBD), carbothermal vapour phase transport (CTR-VPT) and a hybrid CBD / CTR-VPT method. The best optical …
