Mixed Dimensional Heterostructures under 2D Ferroelectric control – MixDFerro

Submission summary

MixDFerro project targets the elaboration and fundamental study of the structural, electronic, optical properties of novel two dimensional (2D) ferroelectric materials and their van der Waals heterostructures (vdW-h) with 2D and 0D semiconductors. We will first address a set of basic questions such as : “How do the electronic structure, phonon spectrum, polarization properties change with the number of 2D layers ? What are the interfacial coupling mechanisms in 2D/2D ferroelectric and 0D/2D ferroelectric heterostructures ? What are the mechanisms and possible electrical control of the switching of the in plane and out of plane 2D ferroelectric domains ? How implementing arrays of such domains in functional devices in order to modulate the energetic landscape of 0D thin films and 2D semiconductor materials ?”
Based on this basic understanding, we will explore three potential applications which are pivotal for new technologies, where 2D ferroelectrics based vdW-h are expected to be high-added value systems: i) field effect transistor (FET), ii) memory devices, iii) phototransistors.t
To achieve these ambitious goals, the MixDFerro project will combine a set of multidisciplinary skills from its Consortium, including advanced synchrotron radiation characterization methods, local probes, piezoelectric measurements, micro-Raman spectroscopy, transport and optoelectronics measurements, van der Waals heterostructure engineering and theoretical modeling of their properties.
