Schematic of the thermal spin device based on the 8-ZGNR-H(N,B)/8-ZGNR-H heterojunction: The device is divided into three regions: the left electrode, the right electrode, and the scattering region. The scattering region also contains three regions: the center heterogeneous region and two buffering regions which are duplications of the left and right electrodes in order to screen the interaction between the electrodes and the center region. A vacuum region of 15 Å is used to eliminate the interactions between adjacent layers (y direction). The integers are the ordinal number of zigzag C chains across ZGNR (x direction). The right electrode is a pure 8-ZGNR-H and the left electrode is a 8-ZGNR-H doped with N at 2 site and B at 7 site respectively, which are semi-infinite in the transport direction (z direction).
