Jee and Yoonho’s paper on the bias-induced ion migration in 2D perovskite heterostructures have been published in Matter. Congratulations!
We fabricate a 2D perovskite single-crystal heterostructure device that can visualize real-time movement of halide anions under external electric bias. Directional movement as well as the favored channels of ion migration are investigated, while post-migration device characteristics are revealed to exhibit asymmetry due to directional ion migration. Read the full story here. A temporary sharable link here.
