2Highly ordered lead-free double perovskite halides by design显示文摘Lead-free double perovskite halides are emerging optoelectronic materials that are alternatives to leadbased perovskite halides.Recently,single-crystalline double perovskite halides were synthesized,and their intriguing functional properties were demonstrated.Despite such pioneering works,lead-free double perovskite halides with better crystallinity are still in demand for applications to novel optoelectronic devices.Here,we realized highly crystalline Cs2AgBiBr6 single crystals with a well-defined atomic ordering on the microscopic scale.We avoided the formation of Ag vacancies and the subsequent secondary Cs3Bi2Br9 by manipulating the initial chemical environments in hydrothermal synthesis.The suppression of Ag vacancies allows us to reduce the trap density in the as-grown crystals and to enhance the carrier mobility further.Our design strategy is applicable for fabricating other lead-free halide materials with high crystallinity.Chang Won Ahn Jae Hun Jo Jong Chan Kim Hamid Ullah Sangkyun Ryu Younghun Hwang Jin San Choi Jongmin Lee Sanghan Lee Hyoungjeen Jeen Young-Han Shin Hu Young Jeong Ill Won Kim Tae Heon Kim 2020Journal of Materiomics2020,6,4:2

13An efficient selectivity estimation method for spatial query optimization with topological relationships显示文摘Many commercial database systems maintain histograms to summarize the contents of relations and permit the efficient estimation of query result sizes and the access plan cost. In spatial database systems, most spatial query predicates are consisted of topological relationships between spatial objects, and it is very important to estimate the selectivity of those predicates for spatial query optimizer. In this paper, we propose a selectivity estimation scheme for spatial topological predicates based on the multi dimensional histogram and the transformation scheme. Proposed scheme applies two partition strategy on transformed object space to generate spatial histogram and estimates the selectivity of topological predicates based on the topological characteristics of the transformed space. Proposed scheme provides a way for estimating the selectivity without too much memory space usage and additional I/Os in most spatial query optimizers.CHUNG Warn ill CHOI Jun ho BAE Hae young 2004重庆邮电学院学报(自然科学版)2004,16,5:0
