Intermetallic compounds: from crystal structure to physical properties
Intermetallic compounds are very promising components for material design. Here we discuss relationship between crystal structure, atomic interactions and physical properties of intermetallic compounds. For example, intermetallic clathrates attracted attention of material’s developers due to their promising thermoelectric activity. The electron localizability approach allows differentiation of covalent and ionic contributions to the atomic interactions. With new tools the formation of the lone pairs around the defects in the covalent Ba-‐Au interactions were detected in the clathrate Ba8AuxGe46-‐x-‐y□y[1]. These findings yield the special features of the electronic density of states, which were confirmed by measurements of electronic and thermal transport. Another new bonding-‐based concept dealing with the intermetallic phases is isolated-‐site model for catalysis. New catalysts for semi hydrogenation of acetylene – based on the well crystallized intermetallic compounds MmPdn of palladium with M = Ga or In [2-‐4], and Al13M4 (M = Fe, Co, …) [5, 6] -‐ were suggested, employing the ideas of the covalent atomic interactions in intermetallic compounds.
