“…Chanelling Rutherford backscattering spectroscopy would be a technique of choice for this purpose, but typically requires single crystals. This is a limitation for MAX phases, which are essentially made as polycrystaline pellets or as thin films, and rarely exist as single crystals [19,20,21].…”

Contribution of core-loss fine structures to the characterization of ion irradiation damages in the nanolaminated ceramic Ti3AlC2

The effect of low energy ion irradiation in the nanolaminated Ti 3 AlC 2 is investigated by means of X-ray diffraction, transmission electron microscopy, electron energy loss and X-ray absorption spectroscopy. The chemical sensitivity and local order probing from core-loss edges provide new insight in the undertanding of structural modifications induced under irradiation. From the analysis of the C K energy loss near edge structure (ELNES) and Al K X-ray absorption near edge structure (XANES) by ab initio calculations, the influence of the layered structure of this compound on the irradiation damage is demonstrated, with preferentialy localized damage in aluminum planes of the structure. On the basis of comparisons between calculations and the experimental spectra, a strutural model is proposed for the irradiated state. This study emphasizes the utility of core-loss fine structure analysis to further understanding of ion irradiation induced damage in complex crystalline materials.

“…Since 2004, however, several new 413 phases have been discovered; first with the synthesis of Ti 4 SiC 3 and Ti 4 GeC 3 thin films [5][6] and then bulk synthesis of Ta 4 AlC 3 in the form of polycrystals [7][8][9][10] and single crystals [11]. More recently, the 413 phases V 4 AlC 3 [12][13], Nb 4 AlC 3 [14], and Ti 4 GaC 3 [15] were also synthesized in bulk form.…”

“…Bulk Cr2GaC can also be formed from a metallic melt of the elements, generated by an excess Ga, at 1300 °C [5]. MAX phases in general have previously been synthesized as thin films using physical vapour deposition (PVD) methods such as magnetron sputtering [6] and cathodic arc [7], with process temperatures considerably lower than those of bulk synthesis.…”

Ab‐initio calculations have been used to investigate the phase stability and magnetic state of Crn+ 1GaCn MAX phase. Cr2GaC (n = 1) was predicted to be stable, with a ground state corresponding to an antiferromagnetic spin configuration. Thin‐film synthesis by magnetron sputtering from elemental targets, including liquid Ga, shows the formation of Cr2GaC, previously only attained from bulk synthesis methods. The films were deposited at 650 °C on MgO(111) substrates. X‐ray diffraction and high‐resolution transmission electron microscopy show epitaxial growth of (000ℓ) MAX phase.
