Direct Integration of Conductive, Emissive Perovskite Nanocrystals Into Efficient Light‐Emitting Diodes Without Post‐Synthetic Ligand Exchange

open access: yesAdvanced Functional Materials, EarlyView.
We demonstrate the direct integration of CsPbBr3 perovskite nanocrystals (PNCs) into optoelectronic devices without post‐synthetic ligand exchange. This is achieved by synthesizing PNCs stabilized by strong‐binding‐energy oleylammonium–bromide pairs instead of oleate ligands. The resultant low ligand density and minimized surface defects enhance charge

Low‐energy electron diffraction with energy resolution

Review of Scientific Instruments, 1992
Low-energy electron diffraction (LEED) is a well established technique for evaluation of the surface atom arrangement. The information is derived from the elastically scattered electrons. Usually the thermal diffuse background between diffraction spots is assumed to be constant and subtracted as a constant. For spot profile analysis, which provides the
