Datasets for In Situ Exfoliation Method of Large-Area 2D Materials publication. Extreme UV photoemission band mapping of 2D materials WS2, WSe2 and WTe2 exfoliated in ultra-high vacuum on Au(111), Ag(111) and Ge(001), and AgTe alloy on Ag(111). Measurements were conducted at the BALTAZAR facility in Stockholm, Sweden using a laser-based setup with arepetition rate of 250 kHz, and the fifth harmonic 18.1 eV, and at the SGM-3 beamline of the 3rd-generation ASTRID2 synchrotron radiation source in Aarhus, Denmark with a photon energy 49 eV, 53 eV and 63 eV. All measurements were performed at room temperature. Experimental data are provided in ibw format (Igor Pro).
