Tunable topological chirality in ferroelectric nanomaterials

Project description

Chirality in nanomaterial fabrication and operation

It may sound tricky: molecules that are non-superimposable mirror images of each other are said to be chiral. Chirality is one of the most intriguing fundamental phenomena in nature. Materials composed of chiral molecules find broad applications in areas ranging from optics to biology and pharmaceuticals. Scientists recently found that chiral structure can be controlled and switched by cleverly devised field-temperature protocols. The EU-funded FerroChiral project wants to identify, measure, explore and put this chirality into practice, using the unique facilities and excellence of Jozef Stefan Institute in Slovenia. The goal is to optimise fabrication parameters.

Objective

Chirality is one of the most intriguing fundamental phenomena in nature. Materials composed of chiral molecules find broad applications in areas ranging from nonlinear optics and spintronics to biology and pharmaceuticals. However, chirality is usually an invariable inherent property of a given material that cannot be easily changed at will. Very recently we discovered that chiral structure emerges as a basic configuration of polarization field in ferroelectric nanoparticles and nanodots in a form of stable fundamental topological excitations of polarization, Hopfions, and skyrmions, and, importantly, can be controlled and switched by cleverly devised field-temperature protocols.
The key idea of the project is to reveal how this discovered emerging topological chirality will be identified, measured, explored, and put in practice, using the unique facilities and excellence of Jozef Stefan Institute in Slovenia. Accordingly, the research objectives of the FerroChiral MSCA are defined as follows:
- To optimize fabrication parameters enabling the engineering of ferroelectric nanostructures with desirable chiral properties.
- To develop research approaches for revealing and exploring the topological structures of the ferroelectric nanostructures.
- To devise efficient enantioselective procedures and elaborate effective methods for chirality revealing and operation.
The new skills in nanomaterial fabrication and operation, and in building the academia-industry links will be developed for further career pursuit. Also, the project will cluster the FerroChiral action with the complimentary European networks in view of prospective developing long-lasting collaborations.
