| Sumario: | 2D molybdenum disulfide under the microscope The growth kinetics of two-dimensional (2D) molybdenum disulfide (MoS2) atomic layers has been captured using atomic-resolution transmission electron microscopy (TEM). In a regular process, 2D growth is usually performed on a silicon dioxide substrate. This makes studying the atomic-scale structures difficult because small layers can be damaged while transfering onto TEM grids. A team led by Chuanhong Jin at Zhejiang University, China, grew atomic layers of MoS2 directly on graphene-layer-based TEM grids in a regular chemical vapor deposition system. With this method intermediate and few-nanometer scale layers have been successfully monitored. These results are important for understanding the growth mechanism of MoS2 and other relevant 2D materials. |
