Infrared- and Raman-Spectroscopy Measurements of a Transition in the Crystal Structure and a Closing of the Energy Gap of BiTeI under Pressure

Oleg Yazyev, Ana Akrap, Gabriel Albert Autes

BiTeI is a giant Rashba spin splitting system, in which a noncentrosymmetric topological phase has recently been suggested to appear under high pressure. We investigated the optical properties of this compound, reflectivity and transmission, under pressure ...

Observation of Weyl Nodes in Robust Type-II Weyl Semimetal WP2

Joël Mesot, Oleg Yazyev, Quansheng Wu, Gabriel Albert Autes

Distinct to type-I Weyl semimetals (WSMs) that host quasiparticles described by the Weyl equation, the energy dispersion of quasiparticles in type-II WSMs violates Lorentz invariance and the Weyl cones in the momentum space are tilted. Since it was propose ...

Electronic Instability in a Zero-Gap Semiconductor: The Charge-DensityWave in (TaSe4)(2)I

Helmuth Berger, Marco Grioni, Oleg Yazyev, Alberto Crepaldi, Luca Moreschini, Gabriel Albert Autes, Simon Karl Moser, Cédric Tournier-Colletta

We report a comprehensive study of the paradigmatic quasi-1D compound (TaSe4)(2)I performed by means of angle-resolved photoemission spectroscopy (ARPES) and first-principles electronic structure calculations. We find it to be a zero-gap semiconductor in t ...

Controlling edge states in the Kane-Mele model via edge chirality

Oleg Yazyev, Gabriel Albert Autes

We investigate the dependence of band dispersion of the quantum spin Hall effect (QSHE) edge states in the Kane-Mele model on crystallographic orientation of the edges. Band structures of the one-dimensional honeycomb lattice ribbons show the presence of t ...

Two-Orbital Kondo Screening in a Self-Assembled Metal Organic Complex

Oleg Yazyev, Harald Brune, Stefano Rusponi, Marina Pivetta, Gabriel Albert Autes, Fabio Donati, Luca Gragnaniello, Giulia Elisabetta Pacchioni

Iron atoms adsorbed on a Cu(111) surface and buried under polyphenyl dicarbonitrile molecules exhibit strongly spatial anisotropic Kondo features with directionally dependent Kondo temperatures and line shapes, as evidenced by scanning tunneling spectrosco ...

Bulk and surface band structure of the new family of semiconductors BiTeX (X=I, Br, Cl)

Helmuth Berger, Arnaud Magrez, Marco Grioni, Oleg Yazyev, Philippe Bugnon, Alberto Crepaldi, Gabriel Albert Autes, Luca Moreschini, Simon Karl Moser, Jens Christian Johannsen

We present an overview of the new family of semiconductors BiTeX (X = I, Br, Cl) from the perspective of angle resolved photoemission spectroscopy. The strong band bending occurring at the surface potentially endows them with a large flexibility, as they a ...

Electronic properties of incommensurately modulated novel and complex materials

László Forró, Oleg Yazyev, Philip Johannes Walter Moll, Alla Arakcheeva, Ana Akrap, Sergiy Katrych, Gabriel Albert Autes, Edoardo Martino

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

Helmuth Berger, Marco Grioni, Oleg Yazyev, 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 ...
