“…2 Several classes of HMMs have been fabricated experimentally or predicted theoretically, e.g., Heusler alloys, metallic oxides, transition-metal pnictides and chalcogenides, etc. [3][4][5] In addition to HMMs, half-semiconductors (HSCs) 6 are also a class of spintronic materials with 100% spin polarization, because their conduction band and valence band are spin split with the conduction band minimum and valence band maximum possessing the same spin channel ( Fig. 1(b)).…”
