摘要
氧化鋁薄膜、氧化鎂薄膜、鑽石薄膜被廣泛的應用在工業界和學
術的研究上,因為它們有不活潑、高穩定性、高電阻率的特性。
而它們可應用在二次電子放大管中,又因為它們都具有相對高的
二次電子放大係數,目前微結構技術的進步,dynodes 可做得非常細
緻,所以可做出性能佳的光電倍增器,dynodes 的形狀可經過微影、
蝕刻…等技術目前可做出不同形狀如三角錐狀(pyramid hole type)
和歪斜狀(slanting hole type)
的dynode,以讓電子擴大現象更明
顯。
基於奈米碳管顯示器的瓶頸,在於像素的亮度與發光源的均勻
性,所以假如把dynodes 置於在電子源跟螢光幕之間,讓二次電子
數目在多次撞擊 dynodes 後增加,而使分布範圍更為寬廣,因而讓
像素變的比較亮比較均勻。
本研究裝置一台二次電子放大係數量測系統,dynode(電子放大
極板)材料為鐵鎳合金,將待測物鍍在dynode 片上,然後在二次電
子放大係數量測系統做偵測,本研究的目的就是找出可以鍍在dynode
片上,又有不錯的二次電子放大係數的材料,目前實驗出氧化鋁薄
膜、氧化鎂薄膜、鑽石薄膜都有不錯的放大係數,而在表面層鍍上薄
層導體Al,有克服電荷累積提升二次電子放大係數的現象。
