Two-terminal devices are building blocks in photonic and electronic systems. They can be active devices such as light-emitting devices 1,2, Schottky diodes 3, solar cells 4 and photodetectors 5 and ...
Significant progress has been made in perovskite light-emitting diodes (PeLEDs) over the past decade, with external quantum efficiencies (EQEs) exceeding 30% for green and red emissions, and 20% for ...
