Photophysics, Photochemistry, and Electronic Properties of Alkalides and Electrides

这项更新建议的重点是研究光学和 碱金属、碱土金属和混合体系的电子性质， 确定电子-电子相互作用的性质， 具有弱俘获电子的结晶固体， 导致电子自旋配对，以及金属-非金属的性质 过渡。 薄膜、微晶膜和单晶 将制备这些材料的晶体，并且它们的发射， 反射，透射和荧光光谱研究。 的 粉末的电导率和阻抗谱， 单晶将被确定，其光电子和 电子发射的研究。

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.
