Abstract: 先端に金属終端（１００）面が形成されたＬａＢ ６ 等の六ホウ化金属ナノワイヤーは、仕事関数が小さいことにより、この（１００）面から非常に細い電子ビームを放射することができるが、低温で使用すると、ごく短時間に汚染されて出力電流が大きく低下してしまう。そこで、先端の金属終端（１００）面を低温で水素に曝露する安定化処理を施すことで、長時間安定動作する冷電界エミッターとした。
Abstract translation: 由于诸如LaB 6的六硼化物金属的纳米线，在其前端形成有金属端子（100）的表面，具有小的功函数，可以从该端子（100）面辐射非常窄的电子束 。 然而，如果在低温下使用，污染就会在很短的时间内积累，输出电流大大下降。 提供一种冷场发射器，其通过前端的金属端子（100）面的稳定化处理在长时间内稳定地工作，其中所述金属端子（100）面在低温下暴露于氢。

Abstract: A metal hexaboride nanowire such as LaB6 with the formed metal-terminated (100) plane at the tip has a small work function, and can emit a very narrow electron beam from the (100) plane. In such emitters, contamination occurs in a very short time period, and the output current greatly decreases when used under low temperature. The cold field emitter of the present invention overcomes this problem with a stabilization process that exposes the metal-terminated (100) plane of the tip to hydrogen at low temperature, and can stably operate over extended time periods.
