Observation of dimension-crossover of a tunable 1D Dirac fermion in topological semimetal NbSixTe2
Observation of dimension-crossover of a tunable 1D Dirac fermion in topological semimetal NbSixTe2
Abstract Condensed matter systems in low dimensions exhibit emergent physics that does not exist in three dimensions. When electrons are confined to one dimension (1D), some significant electronic states appear, such as charge density wave, spin-charge separations, and Su-Schrieffer-Heeger (SSH) topological state. However, a clear understanding of how the 1D …
