Exploration of a New Class p-type Conducting Oxide Based on the Strong Correlation Effect

Transparent conducting oxides (TCOs) have been researched for several decades thus utilizing in many technology advances especially on display area. While such an advance p-type TCO entry is still rare compared to the n-type one as hindering the next generation oxide-based electronics. This article briefly introduces materials design concepts on typical TCOs, and a new approach to realize a high-performance p-type TCO based on strong electron correlation effect.
