Background Perovskites have widely been considered as promising next-generation materials for future display and solid-state lighting applications. Most current perovskite LEDs are produced using solution processing, and over 20% external quantum efficiencies (EQE) in LEDs have been achieved in recent studies. Vacuum-based deposition has also attracted...

­Node classification in real-world attributed networks is a central analytical task that is a growing research area. In real-world networks, a large portion of node classes only contain limited labeled instances. Many prevailing graph machine learning methods typically rely upon the availability of sufficient labeled data. However, the long-tail...

Organic light emitting devices (OLEDs) are a new generation of display technology. OLEDs with polarized light are optimal for mobile displays or other full color display applications. To enable a high quality of full color displays, a polarizer may be paired with a transparent electrode of an OLED. This filters unwanted reflected light from the background...
