Abstract

[Ca24Al28O64]4+(4e-) is a new inorganic electride, which is air-stable even at ∼ 300°C. Its electron field-emission properties originate from electron anions encaged in subnanometer-sized cages embedded in its crystal structure. und the emission current is controlled by Fowler-Nordheim field emission at high electric fields (see Figure). Field-emission display devices demonstrate bright light emission clearly visible under ambient light (inset).
