Identifying Contact Barrier Types in Few-Layer MoS2 Devices Using Correlative IV, LBIC, and Bias-Dependent KPFM
Ariane Ufer, Zeinab Eftekhari, Benjamin Mayer +4
Electrical contacts between metals and two-dimensional (2D) semiconductors such as molybdenum disulfide (MoS2) critically govern device performance, yet their microscopic nature re…
Dielectric Tensor of CrSBr from Spectroscopic Imaging Ellipsometry
Pierre-Maurice Piel, Sebastian Schaper, Aleksandra Åopion +4
Chromium sulfur bromide (CrSBr) is a magnetic van der Waals semiconductor with a direct bandgap and pronounced anisotropy in its electronic, optical, spin and lattice degrees of fr…
Defect-Mediated Phase Engineering of 2D Ag at the Graphene/SiC Interface
Arpit Jain, Boyang Zheng, Sawani Datta +23
Atomically thin silver (Ag) films offer unique opportunities in plasmonic, quantum optics, and energy harvesting, yet conventional growth methods struggle to achieve structural con…
Unambiguous determination of optical constants and thickness of ultrathin films by using optical anisotropic substrates
Sebastian Schaper, Matthias Duwe, Ursula Wurstbauer
The unambiguous and universal determination of optical constants such as complex refractive indices (n, k) and thickness (d) in one measurement is typically confined for films with…
