Charge balance is important to achieve enhanced electrical and optical properties of QD-LEDs. To improve charge balance, we introduce a sol-gel processed method via adding gallium (Ga) into the ZnO-based ETL. GaZnO films can control carrier injection and transport, leading to facilitate charge balance.
