“…1,3 These properties are desirable for several important technological applications to which it is expected that electrides can be successfully applied. For example electron emitters, 4 ion sources, 5 light emitting diodes (LED) devices, 6 nonlinear optical switchers, 7 superconductors, 8 and catalysts, 9,10 for e.g. the synthesis of ammonia, 11 are all areas of active investigation for electrides.…”
