Mechanical strength and electronic instabilities in ultra-incompressible platinum dinitrides
Original language description
The mechanical properties and electronic structure of recently synthesized PtN2, proposed as a potential candidateforsuperhardmaterials,havebeeninvestigatedbymeansofdensityfunctionaltheory.Althoughitshows aclearbandgapindicatingacovalentbondingnature,thecalculatedshearmoduliandidealstrengthsofbothproposedPtN2 polymorphsaremuchlowerthanthoseofReB2,suggestingthatitshouldbeweakerthanReB2,whose load-invarianthardnessislessthan30GPa.TheanisotropicstrengthofthepyritePtN2 polymorphissigni?cantly higher than that of the ?uorite polymorph due to a larger covalent contribution. The shear instability for both polymorphs occurs in a cleavagelike mode between the weakly bonded crystal planes. This behavior is different from transition-metal (TM) diborides where theTM-TM or TM-B bonds are the carriers of the shear instability.
