フィールドエミッタアレイの新しい応用技術～耐熱・耐放射線素子や光源応用に向けて～

抄録

　This review describes novel applications of field emitter arrays. Firstly, the advantages of the field emitter arrays are described on the basis of theoretical arguments on the field electron emission. Secondly, typical characteristics of the vacuum triode are shown. Because an electron beam in vacuum is affected neither by temperature variations of the environment nor by radiation, field emitter arrays are expected to be used under high and/or low temperatures, and also in radiation field. Novel applications of field emitter arrays including radiation tolerant image sensor, charge neutralizer for ion implanter, and electron source for lighting device are described.
