G0w0 calculations
WebG 0 W 0 calculations performed on β-Ni (OH) 2 and β-NiOOH reveal electronic structures consistent with previous experimental results. WebThe GW method is a standard method to calculate the electronic band structure from first principles. It has been applied to a large variety of semiconductors and insulators but less often to metallic systems, in particular, with respect to a self-consistent employment of the method. In this work, we take a look at all-electron quasiparticle self-consistent GW …
