Halide perovskites have attracted tremendous attention from many researchers recently, particularly for their excellent optoelectronic properties in applications such as photovoltaic solar cells and light-emitting diodes. In recent years, the application of halide perovskites has rapidly extended into nanoelectronics, such as thermoelectric, memory, and artificial synapse applications. Halide perovskites can be synthesized easily, even at relatively low temperatures, and organic and inorganic ions can even coexist in one crystal structure. Moreover, the structural flexibility is excellent, where two- and three-dimensional crystals can be linked together. The combination of various types of halide ions not only controls the physical properties of the halide perovskite, but also facilitates control of the bandgap by varying the size of nanoparticles when they exhibit quantum effects. Halide perovskites thus provide an excellent platform for optoelectronics with interesting optical, electrical, and magnetic properties. The articles in this issue introduce the wide range of basic properties and potential applications of halide perovskites.

卤化物钙钛矿材料和装置

卤化物钙钛矿最近引起了许多研究者的极大关注,特别是由于其在光伏太阳能电池和发光二极管等应用中的优异光电性能。近年来,卤化物钙钛矿的应用已迅速扩展到纳米电子学领域,例如热电,记忆和人工突触应用。即使在相对较低的温度下,卤化物钙钛矿也可以轻松合成,并且有机离子和无机离子甚至可以共存于一种晶体结构中。此外,在二维和三维晶体可以连接在一起的情况下,结构柔韧性极好。各种卤离子的组合不仅控制着钙钛矿卤化物的物理性质,但是当纳米粒子表现出量子效应时,通过改变纳米粒子的尺寸,也有助于控制带隙。卤化物钙钛矿因此为光电子提供了一个极好的平台,具有有趣的光学,电和磁特性。本期文章介绍了卤化钙钛矿的各种基本性能和潜在应用。
