perovskite 鈣鈦礦

Many firms, both small and large, see promise in perovskites. These are compounds that share a crystal structure and are named, collectively, after the mineral that was the first substance found to have this structure. Often, they are semiconductors. This means that, like the most famous semiconductor of all, silicon, they can be used in solar cells http://econ.st/1JLrtuF

鈣鈦礦是指一類陶瓷氧化物，其分子通式為ABO₃；此類氧化物最早被發現者，是存在於鈣鈦礦石中的鈦酸鈣(CaTiO₃)化合物，因此而得名。由於此類化合物結構上有許多特性，在凝聚體物理學方面應用及研究甚廣，所以物理學家與化學家常以其分子公式中各化合物的比例(1:1:3)來簡稱之，因此又名「113結構」。
