Quantum spin Hall phase transition in the lattice
J Wang, JF Liu - Physical Review B, 2021 - APS
We report a theoretic study of the topological properties of the α-T 3 lattice by taking the
intrinsic spin orbit interaction into account. It is shown that when 0< α< 1, the electronic band …

Pure crossed Andreev reflection assisted transverse valley currents in lattices
W Zeng, R Shen - Physical Review B, 2022 - APS
We propose a method for the generation of the transverse valley currents, which is based on
the pure crossed Andreev reflection (pCAR) in the superconducting hybrid junctions …

Valley filtering in strain-induced quantum dots
We test the valley-filtering capabilities of a quantum dot inscribed by locally straining an α-T
