Electron Injection Layer Materials

About

Electron injection layer (EIL) materials are used to reduce the work function at the cathode to facilitate efficient charge transport within electronic devices. By reducing the energy barrier, the required operating voltage can be reduced. EIL materials are used particularly in organic light-emitting diodes (OLEDs) where the electron affinity of the materials is typically lower than in other organic electronic devices. The key features of electron injection layer materials are: Reduce barrier for electron injection High electron selectivity and mobility Surface smoothing One example of an electron injection layer material is Liq, commonly used in combination with aluminum to improve the charge transport efficiency of OLED devices. As well as improvements in electron transport, Liq also contributes to enhanced operational stability. Browse our range of electron injection layer materials to improve OLED device performance.
