Hybrid 2D Atomic Crystal-Supramolecular Polymer Heterostructures for Energy-Efficient Memory Transistors

Hybrid inorganic-organic Van der Waals heterostructures provide unprecedented tunability for materials design at both the atomic and molecular scales, enabling new functionalities that surpass those of individual components. This presentation introduces a novel hybrid heterostructure composed of monolayer molybdenum disulfide (MoS₂) and a supramolecular polymer containing crown ether derivatives, serving as a channel material for electrolyte-gated memory transistors. The MoS₂ monolayer functions as an electron-conducting channel, while the supramolecular polymer facilitates extended ion retention, responsible for the memory effect. I will discuss the fundamental mechanisms underlying this memory behavior, highlighting the potential of these hybrid heterostructures for energy-efficient neuromorphic devices.
