Multivalley 3D Electronic Structure of PbSe from Soft-X-Ray ARPES and First-Principles Calculations

Zefeng Cai, Valentine V. Volobuev, Jędrzej Korczak +7

PbSe is a narrow-gap IV-VI semiconductor, whose multivalley valence bands, with maxima at the L, $Σ$ , and $Δ$ points, underpin its intermediate-temperature thermoelectric propertie…

Combining Quasiparticle Self-Consistent $G W$ and Machine-Learned DFT+ $U$ to Assess Half-Metallicity in Co- and Ni-Based Heuslers

Zefeng Cai, Malcolm J. A. Jardine, Maituo Yu +6

Half-metallic Heusler compounds are of significant interest for spintronics. For device fabrication, compounds that can be epitaxially grown on III-V semiconductors are particularl…
