N2 - Two different phases of the transition-metal dichalcogenide and molybdenum ditelluride (1T′-MoTe2 and 2H-MoTe2) were grown by chemical vapor transport. Oxygen-free surfaces were generated by exfoliation in air and then analyzed by x-ray photoelectron spectroscopy. High-resolution core and valence and Auger spectra were acquired for both materials including Te 3d, Te 4d, Te MNN, Mo 3d, and valence band spectra. Differences in Te 3d and Mo 3d peak positions that were previously reported were confirmed, and asymmetry on the metallic 1T′-phase was documented in the Te 3d, Te 4d, and Mo 3d spectra that could prove useful in identifying mixtures of these materials.
