Advanced Science, Volume 12, Issue 6, February 10, 2025.This work proposes a bifunctional design strategy of ferroelectric‐order and electronic‐band to improve the photocurrent and extend the responsive range simultaneously. In a Cu‐doped KTa1−xNbxO3 perovskite crystal, a conductive channel is constructed by “head‐to‐head” ferroelectric domains, associated with the emergence of micrometer‐scale supercells ...
