"MAB phases are a class of layered ternary transition metal borides with large chemical and structural diversity. In this work, we used the Lewis acid etching method to topochemically convert MoAlB into Mo2AlB2 single crystals with a typical size of 0.5–1.5 mm. We comprehensively characterized the single crystals and confirmed the high quality and preferred orientation of the converted Mo2AlB2 crystals using X-ray diffraction, polarized Raman spectroscopy, and transmission electron microscopy. The converted Mo2AlB2 crystals are metallic and exhibit lower resistivity compared to the precursor phase, which is associated with the higher density of states at the Fermi energy of Mo2AlB2 as compared to MoAlB. We show that the chemical conversion is a pathway to produce M2AlB2 phases and this approach can be further extended to other members of M2A2B2 phases for conversion."
