Although epitaxial growth is the fundamental method to realize lattice matched heterojunctions in electronics manufacturing, large-scale single crystal layers based on solution-processing have rarely been reported. Here, cascade organic–inorganic hybrid perovskite crystals with purity quotient over 99.9% consisting of chlorine, bromine, and iodine are fabricated by solution-processed growth, which mismatch rate between adjacent less than 1%.

Urban tracking plays a vital role for people's urban life in intelligent transportation systems, e.g., public safety, case investigation, finding missing items, etc. However, the current methods consume large amount of communication and computing resources since they mainly offload all related sensing data, i.e., videos, generated by widely deployed cameras to cloud where data are stored, processed, analyzed. In this paper, we propose graph optimized offloading algorithm leveraging crowd-AI...
