Design of an Electron Ohmic-Contact to Improve the Balanced Charge Injection in OLEDs
- Published : 2011.02.09
Abstract
The n-doping effect by doping metal carbonate into an electron-injecting organic layer can improve the device performance by the balanced carrier injection because an electron ohmic contact between cathode and an electron-transporting layer, for example, a high current density, a high efficiency, a high luminance, and a low power consumption. In the study, first, we investigated an electron-ohmic property of electron-only device, which has a ITO/
