Importance of surface oxygen vacancies for ultrafast hot carrier relaxation and transport in CuO
Chiara Ricca, Lisa Grad, Matthias Hengsberger +2
CuO has appealing properties as an electrode for photo-electrochemical water splitting, yet its practical performance is severely limited by inefficient charge extraction at th…
High-quality hexagonal boron nitride from 2D distillation
Huanyao Cun, Zichun Miao, Adrian Hemmi +4
The production of high-quality two-dimensional (2D) materials is essential for the ultimate performance of single layers and their hybrids. Hexagonal boron nitride (h-BN) is forese…
Laser-induced asymmetric faceting and growth of nano-protrusion on a tungsten tip
Hirofumi Yanagisawa, Vahur Zadin, Karsten Kunze +7
Irradiation of a sharp tungsten tip by a femtosecond laser and exposed to a strong DC electric field led to gradual and reproducible surface modifications. By a combination of fiel…
Separating the bulk and surface n- to p-type transition in the topological insulator GeBi(4-x)SbxTe7
Stefan Muff, Fabian von Rohr, Gabriel Landolt +5
We identify the multi-layered compound GeBi4Te7 to be a topological insulator with a freestanding Dirac point, slightly above the valence band maximum, using angle-resolved photoem…
Tuning of the Rashba effect in Pb quantum well states via a variable Schottky barrier
Bartosz Slomski, Gabriel Landolt, Gustav Bihlmayer +2
Spin-orbit interaction (SOI) in low-dimensional systems results in the fascinating property of spin-momentum locking. In a Rashba system the inversion symmetry normal to the plane…
Surface and bulk Fermiology and band dispersion in non-centrosymmetric BiTeI
Gabriel Landolt, Sergey V. Eremeev, Yury M. Koroteev +11
BiTeI has a layered and non-centrosymmetric structure where strong spin-orbit interaction leads to a giant spin splitting in the bulk bands. Here we present high-resolution angle-r…
