Broadband Photodetectors and Imaging Arrays Based on PtSe 2 /Si Heterojunctions

ABSTRACT Short‐wave infrared (SWIR) photodetectors are of great importance for applications such as optical communications. However, due to the bandgap limitation of silicon (Si) and the poor compatibility of many SWIR photoactive materials with conventional integrated‐circuit pr...

Heavy‐Halide Coordination and Lattice‐Confined Molecular Alignment Enable Giant Birefringence in Hybrid Metal Halides

ABSTRACT High‐birefringence materials are essential for polarization optics, yet it remains difficult to translate anisotropic molecular building blocks into a strong directionally accumulated crystal‐scale optical anisotropy. Here, we establish a hybrid metal halide engineering...
