At the heart of this project are fundamental properties of thin films growth (mainly oxides) using pulsed laser ablation leading to the development of functional films. These films will partly be incorporated into device structures. The project is divided into two independent sub-projects: Fundamentals of Pulsed Laser Deposition and Thin Films Oxynitride Photocatalysts. The two sub-projects are interrelated with each other, assuring that the involved PhD students can benefit from their cooperations. 1.The sub-project Fundamentals of Pulsed Laser Deposition is aimed at an improved understanding of thin film deposition by pulsed laser deposition, to have a better control over the desired structural and physical properties. The project will be mainly focussed on the composition, structure, and quality of thin films. All of these aspects are strongly influenced by the process parameter and the laser induced plasma properties. 2.The sub-project Thin Films Oxynitride Photocatalysts aims at the growth and characterization of oxynitride thin films use for solar water splitting application. In the solar water splitting process the energy of the light from the sun is converted into chemical energy by generating hydrogen gas which can then be used as a fuel. The interest in oxynitride thin films is in a better fundamental understanding of this class of materials with promising properties.
