Research papers on thin films

Physical and chemical depositions are the two techniques that are used to create a very thin layer of material into a substrate. Physical deposition refers to a widespread range of technologies in that a material is released from the source and which would deposited on a substrate using mechanical, electromechanical or the thermodynamic processes. The two most general techniques of physical vapour deposition PVD are evaporation and sputtering. Chemical deposition is stated as when a volatile fluid precursor does a chemical change on a surface leaving a chemically deposited coating.

When one tries to categorize deposition of films by chemical methods, one would find that they can be categorized into two classes.

The first class is related to the chemical formation of the film from medium and typical methods included are chemical reduction plating, electroplating and vapour phase deposition. A second class is the formation of the respective film from the precursor elements, e. Relationship between the structure and property of thin films is the characteristics of such devices and forms the basis of thin film technologies.

For example, in PVD physical vapour deposition , a pure source material is gasified through evaporation, the application of the high power electricity, laser ablation and other few techniques. The gasified material would then condense on the substrate material to form the desired layer. However, by CVD chemical vapour deposition , the chemical reactions might depend on thermal effects, as in vapour phase deposition and also the thermal growth.

Thin film technology could be applied to various substrate materials, for example ceramics metals or polymers. The very common substrate materials are silicon, steel and glass. Furthermore, currently, thin film technologies are accessible that could be applicable to either flat substrates or objects with multifaceted geometrical silhouettes. Highlighting on device miniaturization and the technological parameters of alternate processes such as thick film are contributing to the expansion of the thin film industry and to the development of lower cost thin film equipment and processes.

This is usually accomplished by lithography and etching. The construction device process is accomplished by ultimate and packaging steps such as assembly , which differ based on the type of device. Everyone owns a numerous astounding moments to have a high regard for the remarkable engage in regeneration of novel thin film devices, the consequence and the good organization of the assistance offered through thin film devices to extend our prospect, in addition to reward for its fascinated defects to make ourselves with recent technological illusions.

Thin films in general are an enormous field of research both fundamentally and from an applied perspective, with uses ranging from corrosion resistance to photovoltaics and sensors. Since bio-based materials are a relatively novel source material for thin films, the research in this area is at a fresh, exciting stage at the moment. This Research Topic on bio-based polymer thin films and coatings should serve as a forum to present the latest achievements in the field of thin film technology or coating techniques using biopolymers.

Articles on nano composites and hybrid materials, i. This includes studies to tune the basic parameters of the thin films or coatings, e. Besides these basic parameter studies, interaction studies at the interface of polymeric thin films and coatings are within the scope of this Research Topic.

Interactions with water or any other solvents either in liquid or vapor phase are included. The method of preparation of the films and coatings includes, but is not limited to, spin coating, dip coating, spray coating, knife casting, Langmuir-Blodgett deposition, and layer-by-layer assembly. Submissions related to applications of bio-based polymer thin films and coatings are also highly welcome.
