无机电子化合物的研究进展
|
Abstract:
电子化合物是一种以电子为阴离子的材料。近年来无机电子化合物的概念不断扩展，其宿主材料从离子晶体到金属间化合物，物质状态从晶体到非晶固体，电子约束空间从0维到1维、2维甚至3维材料。无机电子化合物由于其低功函特性，在电子学(电子发射体和电子注入材料)和化学(还原剂和电子供体)等领域都具有广阔应用前景。本文介绍了电子化合物的研究历史及发展现状，重点介绍了各类无机电子化合物及其结构、电子特性，对电子化合物材料研究和应用的推进具有重要意义。
Electrides are materials with electrons as anions. In recent years, the concept of inorganic electrides has expanded as the host materials from ionic crystals to intermetallic compounds, the states from crystals to amorphous solids, and the electron confined space from 0-dimensional to 1-dimensional, 2-dimensional and even 3-dimensional materials. Inorganic electrides have broad application pro-spects in the fields of electronics (electron emitter and electron injection materials) and chemistry (reductants and electron donors) due to their low work function properties. In this paper, the re-search history and development status of electrides are introduced, focusing on various inorganic electrides and their structures and electronic properties, which is of great significance to advance the research and application of electrides materials.
