Physical properties of niobium and tantalum nitrides
Abstract
The paper gives experimental data on microhardness, electrical and thermal conductivity, Hall coefficient, and thermal emf of tantalum and niobium nitrides. The electronic structures and phase composition of the compounds are discussed on the basis of the results. The changes in properties which occur when the nitrogen content is increased are the same in both systems. At low nitrogen concentrations the electrical conductivity is mainly of the hole type, and at nitrogen concentrations above about 26 at.% it is electronic.
