Investigation of the excitation energy dependence shows that hot carriers created by a photon energy considerably larger than the bandgap induce structural distortions at nanocrystal surfaces on few picosecond timescales associated with the localization of trapped holes.

Space-Filling Curves as a Novel Crystal Structure Representation for Machine Learning Models

no code implementations19 Aug 2016 Dipti Jasrasaria, Edward O. Pyzer-Knapp, Dmitrij Rappoport, Alan Aspuru-Guzik

While the structure representations based on atom connectivities are prevalent for molecules, two-dimensional descriptors are not suitable for describing molecular crystals.
