Abstract

We have found that large amounts of boron can be incorporated in the NbO₂ lattice without altering its basic distorted rutile structure. The electrical conductivity of the small-polaron conductor, NbO₂, shows a remarkable increase with addition of boron and a change from semiconductor-like to metal-like behaviour. However, no superconductivity is observed down to 4.2K in this system, which lacks a metal-oxygen layer structure.
