Physical properties of KxNi2-ySe2 single crystals
Hechang Lei, Kefeng Wang, Hyejin Ryu +3
We have synthesized K0.95(1)Ni1.86(2)Se2 single crystals. The single crystals contain K and Ni deficiencies not observed in KNi2Se2 polycrystals. Unlike KNi2Se2 polycrystals, the s…

Quantum transport of two-dimensional Dirac fermions in SrMnBi2
Kefeng Wang, D. Graf, Hechang Lei +2
We report two-dimensional quantum transport in SrMnBi single crystals. The linear energy dispersion leads to the unusual nonsaturated linear magnetoresistance since all Dirac f…
