This renewal proposal focuses on a study of the optical and electronic properties of alkalides, electrides and mixed systems to determine the nature of electron-electron interactions in crystalline solids with weakly trapped electrons, factors which lead to electron spin pairing, and the nature of metal-non metal transitions. Thin films, microcrystalline films, and single crystals of these materials will be prepared, and their emission-, reflectance-, transmission-, and fluorescence-spectra studied. The electrical conductivity and impedance spectroscopy of powders and single crystals will be determined, and their photoelectron and thermionic electron emission investigated.

该更新提案重点研究碱化物、电子化合物和混合系统的光学和电子性质，以确定具有弱俘获电子的结晶固体中电子-电子相互作用的性质、导致电子自旋配对的因素以及金属-非金属转变的性质。 将制备这些材料的薄膜、微晶膜和单晶，并研究它们的发射光谱、反射光谱、透射光谱和荧光光谱。 将测定粉末和单晶的电导率和阻抗谱，并研究它们的光电子和热电子发射。
