Quantum Efficiency Enhancement of Lead-Halide Perovskite Nanocrystal LEDs by Organic Lithium Salt Treatment
Tassilo Naujoks, Roshini Jayabalan, Christopher Kirsch +9
Surface-defect passivation is key to achieving high photoluminescence quantum yield in lead halide perovskite nanocrystals. However, in perovskite light-emitting diodes these surfa…
Two-dimensional plasmonic polarons in n-doped monolayer MoS2
Fabio Caruso, Patrick Amsalem, Jie Ma +6
We report experimental and theoretical evidence of strong electron-plasmon interaction in n-doped single-layer MoS2. Angle-resolved photoemission spectroscopy (ARPES) measurements…
Temperature-dependent electronic ground state charge transfer in van der Waals heterostructures
Soohyung Park, Haiyuan Wang, Thorsten Schultz +15
Electronic charge rearrangement between components of a heterostructure is the fundamental principle to reach the electronic ground state. It is acknowledged that the density of st…
Microstructure and Elastic Constants of Transition Metal Dichalcogenide Monolayers from Friction and Shear Force Microscopy
Xiaomin Xu, Thorsten Schultz, Ziyu Qin +10
Optical and electrical properties of two-dimensional transition metal dichalcogenides (TMDCs) grown by chemical vapor deposition (CVD) are strongly determined by their microstructu…

Advances in hybrid organic/inorganic architectures for optoelectronics can be achieved by understanding how the atomic and electronic degrees of freedom cooperate or compete to yie…
High Open Circuit Voltages in pin-Type Perovskite Solar Cells through Strontium Addition
Pietro Caprioglio, Fengshuo Zu, Christian M. Wolff +7
The incorporation of even small amounts of strontium (Sr) into lead-based quadruple cation hybrid perovskite solar cells results in a systematic increase of the open circuit voltag…
Stark Effect of Hybrid Charge Transfer States at Planar ZnO/Organic Interfaces
Ulrich Hörmann, Stefan Zeiske, Fortunato Piersimoni +6
We investigate the bias-dependence of the hybrid charge transfer state emission at planar heterojunctions between the metal oxide acceptor ZnO and three donor molecules. The electr…
Space Charge Transfer in Hybrid Inorganic/Organic Systems
