摘要：
W-Cs3Sb, W-TiO2, and W-TiO2-Cs field emission cathodes are fabricated and studied. All these cathodes outperform the conventional tungsten cathode in emission properties: the emission current is very stable and one-and-a-half to two orders of magnitude higher. Physical models of the new emitters are suggested and experimentally verified.
