The pristine atomic structure of MoS2 monolayer protected from electron radiation damage by graphene. Algara-Siller, G., Kurasch, S., Sedighi, M., Lehtinen, O., & Kaiser, U. Applied Physics Letters, 103(20):203107, November, 2013. ![The pristine atomic structure of MoS2 monolayer protected from electron radiation damage by graphene [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex Materials can, in principle, be imaged at the level of individual atoms with aberration-corrected transmission electron microscopy. However, such resolution can be attained only with very high electron doses. Consequently, radiation damage is often the limiting factor when characterizing sensitive materials. Here, we demonstrate a simple and an effective method to increase the electron radiation tolerance of materials by using graphene as protective coating. This leads to an improvement of three orders of magnitude in the radiation tolerance of monolayer MoS2. Further on, we construct samples in different heterostructure configurations to separate the contributions of different radiation damage mechanisms.
