From: Magneto-strain effects in 2D ferromagnetic van der Waal material CrGeTe\(_3\)
ARPES data of CrGeTe\(_3\) measured using (a) 21.2 eV at 300 K (RT), (b) 21.2 eV at 15 K (LT), (c) 84 eV at 300 K (RT) and (d) 84 eV at 15 K (LT). (e) The Brillouin zone showing the direction \(H_2-T-\Gamma -T-H_2\) (in bulk) and \({\bar{K}}-{\bar{\Gamma }}-{\bar{K}}\) (on the surface) where the E-k data are collected and shown in (a)–(d). Band structure calculation using GGA \(+\) U with \(U_{eff}= 0\) and 1 are shown in (f) and (g), respectively.
