Synthesis and Physical Properties of Alkalide and Electride Films and Microcrystals

碱金属阴离子(碱)盐或俘获电子(电子)的盐可以用气相沉积的方法制备成均匀的薄膜，用溶剂挥发的方法制备成微晶膜。光学性质将通过透射谱、反射谱(来自单晶)和荧光光谱进行研究。将测量场发射扫描电子显微镜中的电子能量损失谱。薄膜的导电性和光导性将在气相沉积装置中测定。将使用专门的设备和气相沉积系统来研究光电子发射和热离子电子发射。对碱、电和混合体系的光学和电学性质的研究应该能够确定电子的性质。晶体固体中的电子与弱俘获电子的相互作用，导致电子自旋配对的因素，以及在类似金属氨溶液的晶体中的金属.非金属转变的性质。电子在电子中的弱结合导致了近红外的热电子发射和光电子发射。这些研究的延伸可能会导致红外光电子发射体的发展。

Salts of alkali metal anions (alkalides) or trapped electrons (electrides) will be synthesized as homogeneous thin films by vapor deposition and as microcrystalline films by solvent evaporation. The optical properties will be studied by transmission spectra, reflectance spectra (from single crystals) and fluorescence spectra. Electron energy loss spectra in a field emission scanning transmission electron microscope will be measured. The conductivity and photoconductivity of thin films will be determined in the vapor deposition apparatus. Photoelectron emission and thermionic electron emission will be studied by using both specialized equipment and the vapor deposition system. The study of the optical and electronic properties of alkalides, electrides and mixed systems should permit determination of the nature of electron.electron interactions in a crystalline solid with weakly trapped electrons, the factors which lead to electron spin pairing, and the nature of the metal.non metal transition in a crystalline analog of metal.ammonia solutions. The weak binding of electrons in electrides leads to thermionic emission and photoelectron emission in the near infrared. Extension of these studies might lead to the development of an infrared photoelectron emitter.
