Controlled Epitaxial Growth of Perovskite Single‑Crystal Heterojunction Arrays for Self‑Powered Imaging (IMAGE)
Caption
- A versatile selective epitaxial growth strategy was developed for fabricating perovskite single-crystal heterojunction arrays, enabling precise control over pixel size, arrangement angle, and crystal orientation.
- The self-powered photodetector arrays based on the single-crystal heterojunction exhibited high sensitivity with a weak-light detection limit of 9 nW cm−2, long-term operational stability, and clear imaging capability under zero bias.
