Hydrogen Activation via Dihydride Formation on a Rh1/Fe3O4(001) Single-Atom Catalyst
Chunlei Wang, Panukorn Sombut, Lena Puntscher +10
Hydrogen activation is a key elementary step in catalytic hydrogenation. In heterogeneous catalysis, it usually proceeds through dissociative adsorption on metal nanoparticles foll…
Radio-frequency charge detection on graphene electron-hole double quantum dots
Katrin Hecker, Samuel Möller, Hubert Dulisch +10
High-fidelity detection of charge transitions in quantum dots (QDs) is a key ingredient in solid state quantum computation. We demonstrate high-bandwidth radio-frequency charge det…
Multi-Technique Characterization of Rhodium Gem-Dicarbonyls on TiO(110)
Moritz Eder, Faith J. Lewis, Johanna I. Hütner +12
Gem-dicarbonyls of transition metals supported on metal (oxide) surfaces are common intermediates in heterogeneous catalysis. While infrared (IR) spectroscopy is a standard tool fo…
Corrugation-dominated mechanical softening of defect-engineered graphene
Wael Joudi, Rika Saskia Windisch, Alberto Trentino +7
We measure the two-dimensional elastic modulus of atomically clean defect-engineered graphene with a known defect distribution and density in correlated ultra-high va…
Current-induced brightening of vacancy-related emitters in hexagonal boron nitride
Corinne Steiner, Rebecca Rahmel, Frank Volmer +9
We perform photoluminescence measurements on vacancy-related emitters in hexagonal boron nitride (hBN) that are notorious for their low quantum yields. The gating of these emitters…
Strain engineering of valley-polarized hybrid excitons in a 2D semiconductor
Abhijeet M. Kumar, Douglas J. Bock, Denis Yagodkin +11
Encoding and manipulating digital information in quantum degrees of freedom is one of the major challenges of today's science and technology. The valley indices of excitons in tran…
