Abstract

Interface interactions are generally classified into solid-liquid, solid-gas, solid-vacuum, liquid-gas, light-matter and electron-matter categories. Surface morphological studies as well as surface chemical reactions can be studied in various types of complex systems thanks to technological advances in materials characterization methods. By employing interface engineering in different applications, it is possible to control electrical, chemical, mechanical, optical and biological properties of materials. Accordingly, we have applied interface engineering in three different areas of energy materials, biomaterials and surface imaging. As a result, firstly, we have introduced a high intensity light flash-based method on engineered substrates for delamination of reduced graphene oxide to synthesize electrodes for supercapacitor applications. Secondly, we used the produced electrodes for extreme temperature energy storage. In biomaterials sphere, we investigated the effect of cold plasma on prosthetic implants to improve their surface properties. Raman imaging of brain tissue is the last chapter of this dissertation that deals with the application of light-matter interactions at biological interfaces. We have performed in-depth analyses of various experimental methods for each of the aforementioned topics to introduce novel applications of interface engineering in three different areas.
