Relocation of the topological surface state of Bi${}_2$Se${}_3$ beneath the surface by Ag intercalation

M. Ye, S. V. Eremeev, K. Kuroda +16

We studied the Ag-intercalated 3D topological insulator Bi${}_2$Se${}_3$ by scanning tunneling microscopy/spectroscopy and angle-resolved photoemission spectroscopy, combined with…
