Thin-Film Growth and Oxidation of Surfaces Under Relevant Pressure Conditions

Research output: Chapter in Book/Report/Conference proceedingBook chapterResearchpeer-review

Abstract

The growth of oxides and thin films is important in a wide range of applications, including coating technology, production of solar cell materials, and formation of dielectric layers in the semiconductor industry. These growth processes necessitate the interaction of a solid surface with a gas/vapor or liquid phase. The chemical processes that take place during the interaction of the solid with the second phase have direct impact on the properties of the oxides and films grown, which implies that a true atomic- and molecular-scale understanding of the processes is highly desirable. A true understanding can only be achieved from a monitoring of the phase interfaces at pressures that allow the chemistry to proceed, that is, at relevant pressures. Preferably, monitoring takes place in real time, allowing the identification of atomic and molecular species and a recording of the chemical kinetics. Such monitoring is possible by in situ and operando methods, that is, methods which can be carried out at relevant pressures rather than in vacuum. Limiting ourselves to the solid/vapor interface, we discuss a few of the most important experimental in situ and operando methods and provides examples for their application in the domains of oxidation and thin-film growth.
