제목 Enhancement in Light-Emitting Efficiency by Facilitating Charge Transport in Quasi-Two-Dimensional Perovskite Light-Emitting Diodes.
초록 Low-dimensional perovskite structures have attracted attention in perovskite light-emitting diodes. As it contains large binding energy excitons. However, poor charge transport between two-dimensional perovskite clusters impedes the light-emitting efficiency, because of long ligand chain. Here, we demonstrate a highly efficient low-dimensional perovskite light-emitting diode by realizing improved charge transport properties, mediated by shortening the tunneling barrier length between lead bromides. Acknowledgments We thank the Basic Science Research Program through to NRF funded by the Ministry of Education (2016R1D1A1B03932615) for financial support.
