A combined high-pressure experimental and theoretical study of the electronic band-structure of scheelite-type AWO4 (A = Ca, Sr, Ba, Pb) compounds
high-pressure experimental theoretical study the electronic band-structure scheelite-type AWO4
2011/8/17
Abstract: The optical-absorption edge of single crystals of CaWO4, SrWO4, BaWO4, and PbWO4 has been measured under high pressure up to ~20 GPa at room temperature. From the measurements we have obtain...
On the multi-orbital band structure and itinerant magnetism of iron-based superconductors
Fe-based superconductors Electronic Structure Tight-Binding Downfolding
