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…

Light amplification by stimulated emission from an optically pumped molecular junction in a scanning tunneling microscope
K. Braun, A. M. Kern, X. Wang +5
Here, we introduce and experimentally demonstrate optical amplification and stimulated emission from a single optically pumped molecular tunneling junction of a scanning tunneling…
