摘要：

We　measured　SDDCs　emission　property　and　made　comparison　with　impregnated　scandale　(I-Sc).　A　reasonable　explanation　on　abnormal　Schottky　effect　of　SDDCs　is　given.　The　authors　proposed　a　＇semiconductor-monolayer　superposition＇　model　to　explain　emission　mechanism　of　all　kinds　of　thermionic　cathodes,　including　oxide　cathodes,　M-type　cathodes　and　scandate　cathodes.　Finally,　from　the　view　of　engineering　application,　some　improvement　ideas　and　suggestions　to　future　work　of　SDDCs　are　given.　©　2006　IEEE.
