Topo-electronic transitions in Sb(111) nanofilm: the interplay between quantum confinement and surface effect
PengFei Zhang, Zheng Liu, Wenhui Duan +2
When the dimension of a solid structure is reduced, there will be two emerging effects, quantum confinement and surface effect, which dominate at nanoscale. Based on first-principl…
