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 …

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 …
