Abstract

Results of a detailed theoretical investigation are reported which appear to resolve whether LaN is a semiconductor or a semi-metal. It is found that LaN has a band overlap of approximately 40 mRy making it a semimetal. A detailed analysis of the physical approximations and of the numerical precision indicate that this result has an uncertainty of ∼ 15 mRy which is too small to alter the conclusion.
