Spin and valley filter in strain engineered silicene |
Valley-resolved transmission probability T K ( K′ ) as a function of the incident angle θ for different numbers of alternating normal and strained regions in the system: (a) N = 3, (b) N = 5, (c) N = 7, and (d) N = 9. Parameters are A = 1.9 meV, L = 2.1 nm, E = 2.1 meV, and k F = E /ℏ v F) = 2.2 nm−1. |
