Two-dimensional materials, including graphene, BN and transition metal dichalcogenides (TMDs), exhibit great potential for a variety of applications, such as transistors, spintronics, photovoltaics, or even as window layers for in-situ microscopy holders.[1,2] When 2-dim materials are used in electronic devices, the potential for miniaturization offers remarkable improvements in electrical performance. Yet, the effects of heat dissipation can be a problem in designing electronic devices. Therefore, the thermal properties of 2-dim materials are an important subject of current research and new methods are being developed for temperature measurements at the nanometer scale.[3] In TEM in-situ liquid holders that utilized graphene as a window layer, it was demonstrated that graphene interacts strongly with the contained liquid, which can be beneficial in reducing electron beam induced damage.[4] However, the strong interaction between the reaction species with the graphene window layer can potentially alter the chemistry within the liquid cell and might yield effects not observed in more conventional reactor setups.
