Periodic and non-periodic stacking in molybdenite (MoS2) revealed by STEM.

Results Disordered stacking in molybdenite Micro X-ray diffraction ( -XRD) pattern in Figure 2a revealed that the molybdenite comprised a mixture of 2 I H i SB 1 sb and 3 I R i polytypes (2 I H i SB 1 sb /3 I R i 9:1) ([37]).
