- Abstract
Researchers at the Max Planck Institute for Polymer Research in Mainz have developed single-layer blue OLEDs that only require one layer for light emission. Previously, up to seven-layer materials were used for similar efficiencies. The simpler structure allows for savings in evaporation processes and enables printing. Researchers at RWTH Aachen University have become the first group in Europe to produce a layer of hexagonal boron nitride (hBN), which is used as an insulator in two-dimensional materials. Previously, the majority of hBN worldwide was produced at a materials science institute in Japan. The method used by the researchers in Aachen operates at high temperature but low pressure. A three-layer emitter consisting of HfO2/Ir/HfO2 generates electricity from heat at 1000 °C and maintains its function under these conditions for 100 hours.
