Vanadium Oxide films

ORAL

Abstract

Transition metal oxides with perovskite structures form a fascinating and technologically important class of materials. These compounds exhibit various types of orderings, including ferromagnetic, orbital, and charge ordering, which can interact and coexist in complex and dynamic ways. What makes these systems particularly intriguing is their ability to have these orderings controlled through external stimuli, such as electric, magnetic, or stress fields, resulting in multifunctional properties like piezoelectricity and magnetoelasticity.

In this presentation, we will explore the growth of vanadium oxide thin films, prepared by pulsed laser deposition, and grown on unconventional substrates, like glass templates. We will show how the electronic and optical properties can be influenced with the growth temperature and the thickness of the films. We also demonstrate how a capping layer can be used to enhance thermal stability and improve optical properties. Finally, we will also highlight the potential applications of these films in fields such as optics [1-6]
