Novel materials that couple advanced magnetic and electronic properties are paramount to sustain the hunger of the modern society for advanced consumer electronics and Internet of Things, yet reduce the energy consumption and environmental impact. To satisfy the rather versatile needs of wearable, flexible, integrable, bio-compatible, ever smarter, and low power electronics, the paradigm shift is needed - towards tailored heterostructures, where different functionalities of the constituents are strongly coupled into a multifunctional hybrid. However, such strong interaction between different materials is challenging to realize, as much as their heterostructures are difficult to grow with sufficient control and quality. In this project, we will pursue the stacks of atomically-thin 2D materials as the most versatile yet fully controllable path towards shapeable magnetoelectronics by design. With properties broadly tunable by external mechanical, electric and magnetic stimuli, 2D materials are crystalline systems that nearly ideally connect the simulation environment to their practical behavior and measured quantities. To understand the deeply quantum phenomena behind the flexo-magnetoelectric coupling in 2D heterostructures, yet bridge them over to observables of practical value at micrometer scale, we formed a consortium of leading Belgian teams for suited multiscale simulations, the pioneer of 2D materials in UK for experimental validation, and imec as technology outlet.
