Abstract

Transition metals can play a central role devices such as catalysts, sensors, transistors, or photoluminescence. The existence of an isolated metal atom, sometimes the essential condition to avoid multi-metal deactivation phenomena, requires the presence of a dispersion medium. The solid phase appears advantageous as such dispersion medium for many applications (such as embarked systems, high temperature processes, nanoscale technologies), but defects in the starting solid or lack of control over the positioning of the metal atom can lead to not-ideal final performances of the device.

Thanks to Surface Organometallic Chemistry (SOMC), traditionally applied to the synthesis of single site heterogeneous catalysts, it is possible to control on an atomic scale the positioning and the environment of the active metal grafted on surface. This presentation will introduce the principle of  surface organometallic chemistry on show our latest results in SOMC applied to 2D supports, like silicon wafers, to achieve,  the controlled growth of ultrathin TMD (such as MoSmonolayer by ALD, see Nanoscale, 9, 538 (2017) )
