Spectroscopic Studies of the Electronic Structure in Layered Cuprates and Ruthenates

In materials where electrons interact strongly, a number of exotic and exciting phenomena arise. The mechanisms at the base of many of these phenomena remain debated, as strongly correlated electron physics represents one of the biggest challenges for mode ...

Origin and Magnitude of 'Designer' Spin-Orbit Interaction in Graphene on Semiconducting Transition Metal Dichalcogenides

Helmuth Berger, Zhe Wang

We use a combination of experimental techniques to demonstrate a general occurrence of spin-orbit interaction (SOI) in graphene on transition metal dichalcogenide (TMD) substrates. Our measurements indicate that SOI is ultrastrong and extremely robust, des ...

Evolution of the Valley Position in Bulk Transition-Metal Chalcogenides and Their Monolayer Limit

Dumitru Dumcenco, Yi Zhang, Bo Zhou, Zahid Hussain, Gang Xu, Kai Yan

Layered transition metal chalcogenides with large spin orbit coupling have recently sparked much interest due to their potential applications for electronic, optoelectronic, spintronics, and valleytronics. However, most current understanding of the electro ...

Jahn-Teller versus quantum effects in the spin-orbital material LuVO3

Paul Gregory Freeman, Sándor Tóth, Mechthild Enderle

We report on combined neutron and resonant x-ray scattering results, identifying the nature of the spin-orbital ground state and magnetic excitations in LuVO3 as driven by the orbital parameter. In particular, we distinguish between models based on orbital ...

A Theoretical Rationalisation of the Emission Properties of Prototypical Cu(I)-Phenanthroline Complexes

Ursula Röthlisberger, Ivano Tavernelli, Thomas James Penfold, Gloria Capano

The excited state properties of transition metal complexes have become a central focus of research owing to a wide range of possible applications that seek to exploit their luminescence properties. Herein, we use density functional theory (DFT), time-depen ...

Atomic and electronic structure of a Rashba p-n junction at the BiTeI surface

Marco Grioni, Oleg Yazyev, Helmuth Berger, Philippe Bugnon, Gabriel Albert Autes, Cédric Tournier-Colletta

The non-centro-symmetric semiconductor BiTeI exhibits two distinct surface terminations that support spin-split Rashba surface states. Their ambipolarity can be exploited for creating spin-polarized p-n junctions at the boundaries between domains with diff ...
