Pitfalls in Determining the Electrical Bandwidth of Non-Ideal Nanomaterials for Photodetection
Christine Schedel, Fabian Strauß, Marcus Scheele
The electrical 3 dB bandwidth is regularly used as a measure for the response speed of a photodetector and is estimated via various approaches in literature, ranging from direct me…
Substrate Effects on the Speed Limiting Factor of WSe Photodetectors
Christine Schedel, Fabian Strauß, Pia Kohlschreiber +3
We investigate the time-resolved photoelectric response of WSe crystals on common glass and flexible polyimide substrates to determine the effect of the dielectric environment…
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…
Emergent properties in supercrystals of atomically precise nanocluster and colloidal nanocrystals
Korath Shivan Sugi, Andre Maier, Marcus Scheele
We provide a comprehensive account of the optical, electrical and mechanical properties that emerge from the self-assembly of colloidal nanocrystals or atomically precise nanoclust…
Sub-ns intrinsic response time of PbS nanocrystal IR-photodetectors
Andre Maier, Fabian Strauß, Pia Kohlschreiber +3
Colloidal nanocrystals (NCs), especially lead sulfide NCs, are promising candidates for solution-processed next-generation photodetectors with high-speed operation frequencies. How…
Impact of the Ligand Shell on Structural Changes and Decomposition of All-Inorganic Mixed-Halide Perovskite (CsPbX3) Nanocrystals under X-Ray Illumination
Jan Wahl, Philipp Haizmann, Christopher Kirsch +9
We show that the decomposition of caesium lead halide perovskite nanocrystals under continuous X-ray illumination depends on the surface ligand. For oleic acid/oleylamine, we obser…
