WebIn contrast, the ‘anomalous’ or ‘bulk’ photovoltaic effect (BPVE) in ferroelectrics can create a voltage that is several orders of magnitude higher and scales with the sample thickness. It has been used in the field of photorefractive optics, but its highly efficient energy conversion in domain-engineered ferroelectric structures has ... The upsurge of new materials that can be used for near‐infrared (NIR) photodetectors operated without cooling is crucial. As a novel material with a small bandgap of ≈0.28 eV, the topological crystalline insulator SnTe has attracted considerable attention. Herein, this work demonstrates self‐driven NIR photodetectors based on SnTe/Si and SnTe:Si/Si …
