David Kiefer,Alexander Giovannitti,Hengda Sun et al.
David Kiefer et al.
N-doping of conjugated polymers either requires a high dopant fraction or yields a low electrical conductivity because of their poor compatibility with molecular dopants. We explore n-doping of the polar naphthalenediimide-bithiophene copol...
Postsynthesis Transformation of Insulating Cs4PbBr6 Nanocrystals into Bright Perovskite CsPbBr3 through Physical and Chemical Extraction of CsBr [0.03%]

Francisco Palazon et al.
Perovskite-related Cs4PbBr6 nanocrystals present a "zero-dimensional" crystalline structure where adjacent [PbBr6]4- octahedra do not share any corners. We show in this work that these nanocrystals can be converted into "three-dimensional" ...

Halide perovskites show unusual thermalization kinetics for above-bandgap photoexcitation. We explain this as a consequence of excess energy being deposited into discrete large polaron states. The crossover between low-fluence and high-flue...
