Perovskite Microwire Crystals Encapsulated by Nano‐Grating Structured Small Molecular Film for Polarization‐Sensitive and Highly Stable Photodetectors
Perovskites have emerged as promising materials for high‐performance photodetectors owing to their strong optical absorption, high carrier mobility, and long carrier diffusion lengths. However, their intrinsic instability remains a major obstacle to practical applications. Here, MAPbI3 microwires are encapsulated with...
