Figure 5
(a) The band structure of bilayer Cr2Ge2Te6 under dual regulations (compressive strain of 2% and electron doping of 0.1 e/u.c.). Horizontal dashed lines denote the Fermi level. (b) The schematic of the electronic structures restructuring models under the electron doping (− 0.1 e/u.c.) or dual regulations. Spin-up and spin-down states are marked by red and blue, respectively. The white plane denotes the Fermi surface.
