(a) Schematic for a normal metal (NM)/Dirac semimetal (DSM)/NM junction. The length of the junction is \(L_{x}\). The polarization of the current can be controlled by the barrier, gate and tunneling gate in the junction. (b–e) Dispersions of Dirac semimetals (b) without and (c–e) with Zeeman field. The spin-up and spin-down subband are plotted in blue and red, respectively. The Zeeman terms \((B_{\Delta },B_{0})\) are (b) (0, 0), (c) (0, 0.2), (d) (0.5, 0) and (e) (0.5, 0.2). The dispersions are calculated using the simplified parameters shown in Table 1.
