Cavity space changes insulator to metal
– Elucidation of origin of metallic electronic structure of Na3N –


Hiroshi Mizoguchi, Sang-Won Park, Hideo Hosono (Electro-Active Materials team) and their colleagues reported that the anti-ReO3-type compound Na3N has a metallic nature irrespective of the stoichiometric chemical composition of simple representative elements and that this unusual nature originates from the collapse of the bandgap owing to the presence of a crystallographic cavity.

The results suggest the possibility of sub-nanosized design elements that combine the spatial function of gaps in solid materials with electronic functions, and the introduction of this design will lead to further diversity in the design of inclusion compound materials.
