Résumé
The remarkable electronic properties of graphene have made it a much-studied material, both theoretically and experimentally. In this study, we use an electron spin resonance technique based on terahertz photoconductivity to study the proximity effects of TMDs on graphene. So far, our results do not show any influence of the MoS2 on graphene intrinsic spin orbit coupling and low energy band structure. In addition, we are studying the electron-phonon interaction in encapsulated graphene using magneto-transport measurements. The resistivity depends linearly on temperature for n> 1012 cm-2 and 50K≤T≤200K due to electron-acoustic phonon interaction. For carrier density n > 3.3 1012 cm-2, we observe a slope which seems to indicate a weaker e-ph coupling than predicted and previously reported.
