2019年7月12日，应送彩金的平台王成教授的邀请，比利时蒙斯大学Rony Snyders教授到访，作了题为“Spheres, films, wires, tubes…how can magnetron sputtering be used to synthesize nanomaterials？”的学术报告。来自送彩金的平台、材料科学与工程学院及相关学院的师生参加了此次报告会。
Rony Snyders received his PhD in Chemistry from the University of Mons in 2004. He spend three years as postdoctoral researcher in Polytechnic School of Montreal, Canada and Aachen University, Germany. In 2007 he became associate Professor at the University of Mons and now he is full Professor and head of the Chimie des Interactions Plasma-Surface (ChIPS) group (about 40 persons). He is one of the Scientific Directors of the Materia Nova Research Center, Mons, Belgium and since 2017, he is visiting Professor of our University. He is the present President of the Belgian Vacuum Society, Belvac. His research interests are on the utilization of low pressure plasmas for the processing of materials. He co-authored more than 180 peer-reviewed papers in the fields of thin films synthesis (magnetron sputtering, plasma polymerization,…), of plasma functionalization, and of plasma chemistry and has a H factor of 32.
Chimie des Interactions Plasma-Surface Magnetron sputtering is a technique for synthesizing, most of the time, inorganic thin films. It has been discovered in its initial version by W. R. Grove in 1852 as part of his studies to set up electric lamps. This technique is nowadays largely employed in the industry for example to coat glass windows. Recently, it has been demonstrated that magnetron sputtering could also be used for more “high-tech” approaches, for example, in nanotechnology.
In this presentation, after a short introduction of the basics related to thin films deposition by vapor phase processes and more particularly by magnetron sputtering, we will enjoy a journey in the works that have been developed in our group using magnetron sputtering to grow nano-objects during the last 10 years. In particular, we will see how nanosculpted thin films (in the form of columns, zigzag or helices) can be grown. We will also see how it is possible to synthesize nanotube or nanosphere using magnetron sputtering in combination with the well-known Kirkendall effect. We will then explain how these objects can be used, either in more complex architecture systems for various applications such as in optoelectronic or even to manipulate nanoparticle.
