1 Introduction Transition metal dichalcogenides (TMDs) have emerged as candidates for next-generation optical devices, hosting a range of novel optoelectronic properties even at room temperature.[1-3] A general feature of these systems is the hosting of excitonic states with high binding energies which, through type-II band alignment with other layers, can result in spatial separation of charge carriers by charge transfer (CT).[4] Artificially stacking TMD layers offers a way to modulate...

Electrical Characterisation of Biosensors The electrical performance of 191 individual GFETs with respect to various treatments was examined and is displayed in Figure 3. Since the initial performance of individual GFETs differs considerably from each other (see Figure S7), we use the relative changes of sheet resistance (ΔRs) and Dirac voltage (ΔVDirac) of each GFET to extract actual variance driven by chemical treatment.

Abstract Covalent functionalization of two‐dimensional molybdenum disulfide (2D MoS2) holds great promise in developing robust organic‐MoS2 hybrid structures. Herein, for the first time, we demonstrate an approach to building up a bisfunctionalized MoS2 hybrid structure through successively reacting activated MoS2 with alkyl iodide and aryl diazonium salts. This approach can be utilized to modify both colloidal and substrate supported MoS2 nanosheets.
