Abstract:

This talk reviews the understanding of the materials science of the MAX phases from the point of view of a thin-film physicist. First, a brief overview of thin-film processing methods (sputtering, arc deposition, CVD) will be given, with an emphasis on the characteristic attributes of each method and especially how they relate specifically to processing of MAX phases. In this context, the recent synthesis of numerous new MAX phases (Ti4SiC3, Ta4AlC3, Nb4AlC3, Ti4GaC3,…) will be reviewed, as an important example of an area in MAX-phase research where thin-film synthesis, bulk synthesis, and theoretical predictions and explanations have progressed together. Electrical and mechanical properties are reviewed with an emphasis on features where thin-film processing can contribute to understanding the complex materials science problems involved; in particular, the anisotropy in conductivity, thermopower, and mechanical properties. Finally, important future research directions will be discussed.

Short Bio: 

Per Eklund received his PhD in materials science, in particular thin film physics, from Linköping University, Sweden, in 2007. His thesis topic was multifunctional nanocomposite and MAX-phase carbide thin films in the Ti-Si-C and related materials systems. After a postdoctoral position in 2007-2008 at the Interdisciplinary Nanoscience Center (iNano) at the University of Aarhus, Denmark, he held a 3-month Visiting Senior Researcher position at the Centre National de la Recherche Scientifique (CNRS) in Châtillon (Paris), France. In 2009, he joined the faculty at the Thin Film Physics Division at Linköping University, where he became Associate Professor in nanostructured functional ceramics in 2010. In the summer of 2010, he held a Visiting Full Professor position at the University of Poitiers, France. He has been awarded a Carlsberg Foundation postdoctoral award, and holds an Ingvar Carlsson Award from the Swedish Foundation of Strategic Research as well as major research grants from the Swedish Research Council and the Nordic Council. Apart from the MAX phases and nanocomposite carbides, his research interests include complex thin-film oxide materials for energy applications (e.g., fuel cells) and hard coatings.
