30/06/2017 - Conductivity of monolayer MoS2 measured by Electrochemicl Microscopy
Electronic transport of MoS2 mono-layered flakes investigated by scanning electrochemical microscopy by O. Henrotte, T. Bottein, H. Casademont, K. Jaouen, T. Bourgeteau, S. Campidelli, V. Derycke, B. Jousselme and R. Cornut, ChemPhysChem 2017.
The amazing properties of 2D materials are envisioned to revolutionize several domains such as flexible electronics, electrocatalysis, or biosensing. Herein we introduce Scanning Electrochemical Microscopy (SECM) as a tool to investigate molybdenum sulfide in a straightforward fashion, providing localized information regarding the electronic transport within CVD-grown micrometric size crystalline single-layers of MoS2. Our investigations show that within flakes assemblies some flakes are well electrically interconnected, with no detectable contact resistance, while others are not electrically connected at all independently from the size of the physical contact between them. Overall, the work shows how the complex electronic behavior of MoS2 flake assemblies (semiconducting nature, contact quality between flakes) can be investigated with SECM.

12/05/2017 - A new optical microscopy technique to "see" 2D nanomaterials
► Researchers at CEA-Licsen, CNRS-Le Mans, CNRS-Marseille and Université Libanaise developped a new optical microscopy technique called BALM (Backside Absorbing Layer Microscopy) able to image 2D materials (such as graphene oxide) with high resolution and to follow chemical reactions at surfaces in real time. The study is published this month in Science Advances. It was also commented in NanotechWeb.
