Nanoscale Charge Transport Characterization of Novel Type 2D MOFs and COFs

In recent years, Metal Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs) have emerged as fascinating and promising materials classes, owing to their exceptional structural versatility and tunable properties, which make them interesting for a wide range of technological applications [1,2]. At the same time, the study of 2D van der Waals materials has become the probably most relevant and dynamic area in solid state research at present, offering numerous opportunities to uncover novel physical phenomena and engineer advanced nanoscale devices. With recent advances in the synthesis of two-dimensional MOFs and COFs, these material classes have also entered the field of van der Waals materials [1]. We will characterize the charge transport in novel type 2D coordination network materials like Cu-BHT, considering also the influence of properties like structure or defects. By that, we will demonstrate why they are promising candidates for implementation into van der Waals heterostructures.
