Defect Density and Atomic Defect Recognition in the Middle Layer of a Trilayer MoS₂ Stack.

ABSTRACT: Molybdenum disulfide (MoS₂) is one of the most intriguing two-dimensional materials, and moreover, its single atomic defects can significantly alter the properties. These defects can be both imaged and engineered using spherical and chromatic aberration-corrected high-resolution transmission electron microscopy (C_C/C_S-corrected HRTEM). In a few-layer stack, several atoms are vertically aligned in one atomic column. Therefore, it is challenging to determine the positions of missing atoms and the damage cross-section, particularly in the not directly accessible middle layers. In this study, we introduce a technique for extracting subtle intensity differences in C_C/C_S-corrected HRTEM images. By exploiting the crystal structure of the mate
