The analysis of the comparison of the partial energy distributions of the valence electrons of the ?(C11b)-WGe2 and ?(C23)-WGe2 phases was also studied. The transformation of interatomic bonds during the polymorphic transition ?(C23)-WGe2??(C11b)-WGe2 under comprehensive compression was proposed. The first-principles calculations showed that the phase transition from the ?(C23)-WGe2 phase to the ?(C11b)-WGe2 phase occurs under high pressure. Furthermore, the electronic structure calculations indicate that the considered phases are metallic in nature. The results have revealed that the fine-structure peculiarities of the WL? 5- and GeK? 2-emission bands match well with the main peaks of the partial densities of the W d- and Ge p- electronic states for the both phases.eninfo:eu-repo/semantics/closedAccessElectronic StructureFirst-principles CalculationsPhase TransitionTungsten DigermanidesX-ray Emission BandArticle98510.1088/1402-4896/accc5dQ1WOS:000975366700001Q2
