Boosting Functional Diversification of 2D Materials—From Multiresponsive Hybrid Heterostructures to Neuromorphic Logics

Engineering the interfacing of 2D semiconductors with molecules by making use of principles of supramolecular chemistry represents a powerful strategy to impart multiresponsiveness to 2D materials with the ultimate goal of generating multifunctional hybrid systems for applications in electronics beyond CMOS through the functional diversification following a “more than Moore” strategy. [1]
In my lecture I will present our recent findings on the non-covalent functionalization of 2D materials to engineer hybrid systems via the controlled interfacing of their two surfaces either in a symmetric or asymmetric fashion with molecular switches, thereby imparting additional properties to MoS₂, back phosphorous or WSe₂, rendering 2D material-based transistors capable to respond to as many as four different independent stimuli.[2] Such a strategy enabled to execute complex function thereby emulating neuromorphic-based cognitive processes.[3]

Our modular strategies relying on the combination of 2D materials with molecules offer a simple route to generate multifunctional coatings, foams and nanocomposites with programmed properties to address key global challenges, to ultimately improve the quality of life on our planet.
