Abstract

In the present work, we investigate the electronic structure of the two-dimensional ferromagnet Cr2Ge2Te6 by photoemission spectroscopy and ab initio calculations. Our results demonstrate the presence of multi-hole-type bands in the vicinity of the Fermi level indicating that the material can support high electrical conductivity by manipulating the chemical potential. Also, our photon energy-dependent angle-resolved photoemission experiment shows that several of the hole bands exhibit weak dispersion with varied incident photon energy providing experimental signature for the two-dimensional nature of Cr2Ge2Te6. Thereby, these findings can pave the way for further studies towards the application of Cr2Ge2Te6 in electronic devices.
