Efficient Interlayer Interactions in van der Waals Molecule/TMD Heterostructure

Two-dimensional (2D) materials have emerged as a platform for studying exotic physical phenomena, including excitonic, magnetic, and topological effects. 2D molecules are an area of interest that has recently garnered interest by thrusting the rich field of 2D physics into the realm of chemistry. This significantly increases the number of compounds available for study at the 2D limit. Recently, molecules with unorthodox spin states have helped bridge the gap between physics and chemistry. The interfacial interactions of 2D molecules and van der Waals materials have yet to be studied extensively. We perform optical spectroscopy studies of the hybrid interface between 2D spin-crossover molecules and different types of 2D semiconductors with gating control. This study deepens our understanding of the interaction mechanism and strengths in van der Waals type hybrid interfaces.
