[Wien] Metal or semimetal

I strongly disagree Wikipedia gives a very different definition https://en.wikipedia.org/wiki/Semimetal Bi would be a good example; it has a very low DOS at Ef (with the wikipedia definition of semimetal) Graphite is conductor in the ab plane and a poor conductor (not insulating) in the c

Re: [Wien] Metal or semimetal

Thank you for the Link, but I don't understand your remarks Wikipedia tells: - Schematic C) a semimetal (like tin (Sn) or graphite and the alkaline earth metals). and further - Classic semimetals The classic semimetallic elements are arsenic, antimony, bismuth, α-tin (gray tin) and graphite, an

[Wien] Jeff=1/2 and 3/2 states using case.cf files

Dear Wien2k users, I am studying the Jeff = 1/2 and 3/2 states of an iridate compound. More specifically, I would like to evidence them into bandstructure and/or DOS. I found in the mailing-list the following messages, posted 5 years ago :

[Wien] Effect of spin-orbit coupling on half metal

Dear Wien2k users, I am working on MnFe2O4 cubic structure on wien version 18.2 with OS centos7. In normal GGA calculation, MnFe2O4 shows half-metallic nature. With the inclusion of spin-orbit coupling, it shows metallic behaviour. Can anyone please explain the effect of spin-orbit coupling on

Re: [Wien] Metal or semimetal

I strongly disagree, a semi-metal (not to be confused with a half-metall) is a material that is insulating (semiconducting) in one direction and conducting in another one, a typical example is graphite. (this has nothing to do whether the bands are flat or not; and just to mention, the density
