Speaker-Lapo Bogani
Professor Lapo Bogani held a Marie Curie Fellowship at the CNRS Neél Institute in France (2006-2008) and a Sofja Kovalevskaja Researcher position at the University of Stuttgart (2009-2015). Since 2015, he has been a Royal Society URF Fellow at the University of Oxford, where he was an Associate Professor (2017-2020) and a Full Professor of Molecular Nanomaterials (2020-2023). He is currently an Academic Visitor at Oxford and a Professor at the University of Florence, Italy.
His research focuses on creating and characterizing electronic and magnetic nanomaterials, especially molecular systems. His team studies the properties of nanoscale magnets and integrates these with carbon nanomaterials in electronic and spintronic devices. Their work spans physics, chemistry, and materials science, including the synthesis of novel molecules, development of sensitive instruments, and theoretical simulations. They optimize these materials for applications in quantum technology, energy, information technology, and medicine.
Magnetic states in graphene nanostructures have undergone intense theoretical scrutiny, because their coherent manipulation would be a milestone for spintronic and quantum computing devices. In nanoribbons, experimental investigations now show that quantum coherence of edge and localized graphene states is observable.[1] Several questions remain thus unsolved: how can molecular spins be integrated into electronic structures? Can topological states be used to improve the quantum coherence? Can metals be introduced so as to affect the carbon spin states? Can the quantum spin states be observed in devices? What is the role of electron-electron correlations? Here we try to provide an answer to these questions, exploring spin states in carbon by using molecular synthetic techniques.
Here we show how topological engineering of the carbon lattice can lead to improved coherence, higher than theoretical predictions.[2,3] We then show how such molecular structures can be included into molecular devices, producing magnetoresistive effects that are opposite to non-molecular devices.[4,5,6] The inclusion of metals then allows altering the spintronic properties. [7] We show how such electronic devices show quantum blockade up to room temperature, with different Luttinger liquid regimes available in different ranges.[8] The bright emissive modes offer the possibility of observing the quantum states optically.[9]
