摘要： 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.
摘要翻译： 具有尖端形成的金属端接（100）面的LaB6等金属六硼化物纳米线具有较小的功函数，并能从（100）面发射非常窄的电子束。 在这样的发射器中，污染发生在非常短的时间段内，当在低温下使用时，输出电流大大降低。 本发明的冷场发射器通过将尖端的金属端接（100）面低温暴露于氢的稳定化处理来克服这个问题，并能够在延长的时间段内稳定地工作。
