Deposition and Characterization of Ceramic Thin Films and a New Experimental Approach to Evaluate the Mechanical Integrity of Film/Substrate Interfacial Layers
… designed and constructed ultra-high-vacuum (UHV) vapor phase deposition system was used for the preparation of ceramic thin films through low-pressure high-density plasma assisted physical vapor deposition (PVD) methods. Deposited thin films were characterized by X-ray photoelectron spectroscopy …

Aqueous-Derived Thin Films and their Interfacial Interactions with Semiconductor Surfaces: A Spectroscopic Study
… vacuum-based techniques, such as chemical vapor deposition (CVD), to deposit metal oxide films. These vapor-phase deposition techniques suffer due to their slow deposition rates and their use of expensive equipment. Additionally, these processes sometimes require the use of harmful source …

Origins and implications of intrinsic stress in hydrogenated amorphous silicon thin films
… to be understood about the relationship between deposition conditions and the resulting structural, optical, and bulk properties of the material. In this work we investigate these correlations for a-Si:H films created using plasma enhanced chemical vapor deposition (PECVD), focusing on the …

Fabrication and characterisation of ZnO nanostructures: from nanoscale building blocks to hybrid nanomaterials - towards emerging technologies in sensing applications
… different synthetic techniques ranging from vapor phase deposition (Metal-Organic Chemical Vapor Deposition) to solution growth (Chemical Bath Depo-sition). Moreover, hybrid synthetic approaches are used to obtain complex hier-archical ZnO structures having dual or multiple morphologies. The …

Electrospun and Vapor-Phase Deposited Electroactive Polymer Nanocomposites for Water Purification via Photocatalysis
… onto electrospun nanofibers, first via solution-phase as proof of concept, and later using the more scalable process of vapor-phase deposition (VPD). That is, once TiO2-loaded PAN nanofiber mats were developed, EAP precursors of choice i.e., 3,4-ethylenedioxythiophene (EDOT), pyrrole (Py), 2,2- …

Designing Volatile Molybdenum Compounds for Vapour-Phase Deposition
The vapor phase deposition of many molybdenum-containing films relies on the delivery of volatile compounds with the general bis(tert-butylimido)molybdenum(VI) framework. Herein the preparation and thermal characterization of several adducts of (tBuN)2MoCl2 with various neutral ligands is …

Multiferroic BiFeO3 films and nanostructures for hybrid energy harvesters
… the following work has been focused on the deposition by metal-organic vapor phase deposition of multiferroic BiFeO3 films and nanostructures. BiFeO3 is a multiferroic material and can maintain its properties in extreme environments thanks to its Curie and Neel temperatures well above room …

The Smallest Base and Precious Metal Deposits in the World: Vapor Transport and deposition of Co-Cu-Sn-Ag alloys in vesicles
… for lattice characterization of the exsolved phases and shows a FCC structure for the Cu-Sn section of the alloys. Cu-Sn alloys high in Sn are successfully indexed using the Cu6Sn5 pattern (hexagonal), even though the Sn:Cu ratio of our alloys is considerably lower than 5:6. Cu-Sn alloys …
