a, b Plots of valence-band dispersion (a) and the first-principles calculations (b) of 7 ML CrTe2 with the inclusion of spin polarization along the high symmetry direction M-Г-K. The minority and majority spin bands are plotted in red and blue colors, respectively. The major features seen in the left panel are well reproduced in the right one. c–e Comparison of the valence-band dispersion near the Fermi level taken by He Iα (21.2 eV) (c), He IIα photons (40.8 eV) (d) with theoretical bands (e) along the high symmetry direction M-Г-M. The blue and red dashed lines indicate the position of hole pockets measured by He Iα and He IIα photons, respectively. The light blue/red markers represent the positions of MDC peaks. The error bars represent uncertainties in locating peak positions. f ARPES intensity maps of 1 ML, 2 ML, 3 ML, 5 ML, 7 ML, and 15 ML, respectively. The spectra of various thicknesses were taken along the high symmetry direction M-Г-M.
