Persistence of structural distortion and bulk band Rashba splitting in SnTe above its ferroelectric critical temperature
Frédéric Chassot, Aki Pulkkinen, Geoffroy Kremer +8
The ferroelectric semiconductor -SnTe has been regarded as a topological crystalline insulator and the dispersion of its surface states has been intensively measured with angle-…
Altermagnetic lifting of Kramers spin degeneracy
J. Krempaský, L. Šmejkal, S. W. D'Souza +20
Lifted Kramers spin-degeneracy has been among the central topics of condensed-matter physics since the dawn of the band theory of solids. It underpins established practical applica…
Observation of Weyl and Dirac fermions at smooth topological Volkov-Pankratov heterojunctions
J. Bermejo-Ortiz, G. Krizman, R. Jakiela +6
Weyl and Dirac relativistic fermions are ubiquitous in topological matter. Their relativistic character enables high energy physics phenomena like the chiral anomaly to occur in so…
Extremely low energy ARPES of quantum well states in cubic-GaN/AlN and GaAs/GaAlAs heterostructures
Mahdi Hajlaoui, Stefano Ponzoni, Michael Deppe +6
Quantum well (QW) heterostructures have been extensively used for the realization of a wide range of optical and electronic devices. Exploiting their potential for further improvem…
Surface effects on the Mott-Hubbard transition in archetypal VO
G. Lantz, M. Hajlaoui, E. Papalazarou +9
We present an experimental and theoretical study exploring surface effects on the evolution of the metal-insulator transition in the model Mott-Hubbard compound Cr-doped VO…
Tuning a Schottky barrier in a photoexcited topological insulator with transient Dirac cone electron-hole asymmetry
M. Hajlaoui, E. Papalazarou, J. Mauchain +19
The advent of Dirac materials has made it possible to realize two dimensional gases of relativistic fermions with unprecedented transport properties in condensed matter. Their phot…
Ultrafast surface carrier dynamics in the topological insulator Bi2Te3
M. Hajlaoui, E. Papalazarou, J. Mauchain +9
We discuss the ultrafast evolution of the surface electronic structure of the topological insulator BiTe following a femtosecond laser excitation. Using time and angle reso…
