Quasiparticle band structure of lanthanum hydride

Journal Article · · Physical Review B

We address the problem of the ground-state character of LaH{sub 3}, a semiconductor compound predicted to be semimetallic within density-functional theory. An ab initio, quasiparticle calculation is peformed whose results indicate a very large 1.1 eV opening of the band gap. Such results are obtained using the GW approximation in the calculation of the self-energy operator. The results are compared to existing experimental data.
