Nanolamelar materials

[legende-image]1383921781557[/legende-image]The Mn+1AXn  phases, or “MAX” phases, are nano-laminates where M is an early transition metal, A belongs to groups 13-16 and X is either C or N. They were discovered some decades ago. However, it is only at the end of the 20th century that the possibility to obtain them in the form of almost pure, polycrystalline samples really initiated a research field which has since then been continuously expanding. MAX phase research has received a new impetus a few years ago, after it was demonstrated that many members of this nano-lamellar family could be transformed in two-dimensional (2D) materials called MXenes. Both MAX phases and MXenes attract the interest of the scientific community because they present exceptional conducting and mechanical properties, are highly stable and could be used in a large number of applications, whenever combining the good properties of metals to those of ceramics is sought for (e.g., highly stable volumetric capacitances with extreme capacitance values). Our specificity is the production of single crystals of those phases.

[legende-image]1383921781558[/legende-image]We grow single crystals of MAX phases using high temperature solution growth [6,8] eand determine their physical properties, focusing on the anisotropies expected from their nano-lamellar structure. To cite but a few examples, in collaboration with our various partners, we recently measured magneto-transport [3,7], band structure [4] or phonon dispersion anisotropies of MAX phase single crystals[2]. We also use our crystals for producing MXenes and studying their physical properties [7]. We just started to investigate new magnetic MAX phases and associated Mxenes within the frame of a European project involving LMGP, NEEL Institute, Linköping University (LiU), Université Catholique de Louvain (UCL) and ESRF as main partners. We do not limit ourselves to nano-lamellar carbides, but we also started to develop activities on nano-lamellar borides in collaboration with Drexel (Philadelphia) [5].
