2D High-entropy materials: a new materials class with novel functionalities
Novel materials with improved or new functionalities are behind innovation in virtually every field. Entropy engineering has led to considerable progress and novel functionalities in bulk materials and reducing dimensionality has done the same for 2D materials. The European Research Council-funded HighEntropy2D project will marry these two concepts for the first time with a view to creating 2D high-entropy materials (HEMs) as a new materials class with novel functional properties and potential applications in electronics and catalysis. Reducing HEM dimensionality to 2D will also offer a unique opportunity to study diffusion, crystallisation, phase transition and separation mechanisms in HEMs in situ and at the atomic scale for the first time.
Objective
“Entropy engineering” recently had exceptional impact on bulk materials science by invention of bul“Entropy engineering” recently had exceptional impact on bulk materials science by invention of bulk high entropy alloys and ceramics. The underlying idea is that by equiatomically adding ≥5 principal elements to alloys/compounds, the much increased configurational entropy stabilizes otherwise non-accessible single “high entropy” phases with an unique random elemental occupancy on a crystalline lattice and hence novel functional properties. Likewise, reducing dimensionality in “two-dimensional” (2D) materials recently had exceptional impact on materials science due to the 2D materials’ unique functional properties. Despite these exciting individual prospects of “entropy engineering” and “2D materials”, combination of these two concepts to synergetically create novel 2D high entropy materials (2D HEMs) as a novel materials class with novel functional properties with possible applications in electronics and catalysis remains lacking. In “HighEntropy2d” we will fabricate unprecedented 2D HEMs (2D high entropy alloys, oxides and sulfides) using for the first time scalable vapour deposition and a 2D template/2D confinement approach for both 2D film and 2D nanoflake form, asses their novel properties and perform first tests of their applicability for electronic devices and catalysis. Reducing HEM dimensionality to 2D will also create a unique opportunity to for the first time study in situ and at the atomic scale currently unknown fundamental diffusion, crystallisation, phase transition and separation mechanisms in HEMs (using a globally unique (scanning) transmission electron microscopy ((S)TEM) setup), to obtain fundamental insights relevant to HEMs even beyond the here newly introduced 2D HEMs. The proven track record of principal applicant Bernhard C. Bayer in 2D materials synthesis and atomic scale in situ (S)TEM is an ideal basis for this ambitious research programme.
