Carrier injection and transport materials are key components in OLEDs. We developed novel transparent amorphous oxide semiconductors for this purpose. The materials created are:1. amorphous C12A7 electride for e-injection2. amorphous ZSO for electron transport/injection3. amorphous IMO for hole injection4. ultra wide-gap AOS for NBIS-free TFTs
