MoTe2 gradually oxidises in air forming molybdenum dioxide (MoO2). At elevated temperatures MoTe2 oxidation produces Te2MoO7 and TeMo5O16. Other oxidation products include molybdenum trioxide, tellurium, and tellurium dioxide. Flakes of molybdenum ditelluride that contain many defects have lower luminescence, and absorb oxygen from the air, losing their luminescence. Webleads to the oxidation of the fourth layer. The thickness of oxide layer could be tuning simply by changing O 3 exposure time with atomic-level accuracy, which is more advantageous for realistic applications than the self-limiting oxidation process in WSe 2 13.
