Fig. 4. Constant energy contours of the (a) inner, (b) outer, and (c) middle bands of ABA-stacked trilayer graphene at several different energies with respect to EF. White arrows denote the positions of maximum spectral intensity. (d) Rotational angle of the maximum intensity upon rotating light polarization by π/2 as a function of E – EF in the upper panel and band-selective Berry phase as a function of E – EF converted from the rotational angle in the lower panel. Black, red, and yellow colors denote the inner, middle, and outer bands, respectively.
