Synthesis, Optoelectronic Properties, and Charge Carrier Dynamics of Colloidal Quasi-two-dimensional Cs3Bi2I9 Perovskite Nanosheets
Sushant Ghimire, Chris Rehhagen, Saskia Fiedler +3
Non-toxicity and stability make two-dimensional (2D) bismuth halide perovskites better alternatives to lead-based ones for optoelectronic applications and catalysis. In this work,…
Template Mediated Formation of Colloidal Two-Dimensional Tin Telluride Nanosheets and the Role of the Ligands
Fagui He, Eugen Klein, Stephan Bartling +4
We report the colloidal synthesis of 2D SnTe nanosheets through precursor hot-injection in a nonpolar solvent. During the reaction, an important intermediate - Sn-template - is for…
Structural Reconstruction in Lead-free Two-dimensional Tin Iodide Perovskites Leading to High Quantum Yield Emission
Sushant Ghimire, Kevin Oldenburg, Stephan Bartling +2
We report a structural reconstruction-induced high photoluminescence quantum yield of 25% in colloidal two-dimensional tin iodide nanosheets that are synthesized by a hot-injection…
Role of Magnetic Coupling in Photoluminescence Kinetics of Mn2+-doped ZnS Nanoplatelets
Liwei Dai, Abderrezak Torche, Christian Strelow +8
Mn2+-doped semiconductor nanocrystals with tuned location and concentration of Mn2+ ions can yield diverse coupling regimes, which can highly influence their optical properties suc…
Domain-informed graph neural networks: a quantum chemistry case study
Jay Morgan, Adeline Paiement, Christian Klinke
We explore different strategies to integrate prior domain knowledge into the design of a deep neural network (DNN). We focus on graph neural networks (GNN), with a use case of esti…
Colloidal two-dimensional metal chalcogenides: Realization and application of the structural anisotropy
Ziyi Hu, Ryan O'Neill, Rostyslav Lesyuk +1
Due to the spatial confinement, two-dimensional metal chalcogenides display an extraordinary optical re-sponse and carrier transport ability. Solution-based synthesis techniques su…
