The spin‐gapless semiconductors (SGSs) are a new class of zero‐gap materials which have fully spin polarized electrons and holes. They bridge the zero‐gap materials and the half‐metals. The band structures of the SGSs can have two types of energy dispersion: Dirac linear dispersion and parabolic dispersion. Researchers in Australia review both methods in different material systems and the concepts of the SGS, novel spin and charge states, and the potential applications of SGSs in next‐generation spintronic devices…read more.
