Bipolar junction transistor (BJT) as one important circuit element is now widely used in high‐speed computation and communication for its capability of high‐power signal amplification. 2D materials and their heterostructures are promising in building high‐amplification and high‐frequency BJTs because they can be naturally thin and highly designable in tailoring components properties. However, currently...
In the post‐Moore era, 2D materials with rich physical properties have attracted widespread attention from the scientific and industrial communities. Among 2D materials, the 2D homojunctions are of great promise in designing novel electronic and optoelectronic devices due to their unique geometries and properties such as homogeneous components, perfect lattice matching, and efficient charge transfer...
In article number 2000228, Luying Li, Tianyou Zhai, and co‐workers prepare large‐size BiOCl flakes with thickness down to a monolayer via salt‐assisted chemical vapor deposition. The 2D BiOCl photodetectors exhibit high responsivity throughout the solar‐blind range at room and high temperatures. The success in fabrication of atomically thin BiOCl photodetectors opens opportunities for their potential...
2D wide‐bandgap semiconductors demonstrate great potential in fabricating solar‐blind ultraviolet (SBUV) photodetectors. However, the low responsivity of 2D solar‐blind photodetectors still limits their practical applications. Here, high‐responsivity solar‐blind photodetectors are achieved based on 2D bismuth oxychloride (BiOCl) flakes. The 2D BiOCl photodetectors exhibit a responsivity up to 35.7...
