对金刚石薄膜发射,比较了三极管和四极管的发射特性,以及薄膜面积对发射特性的影响,得出金刚石薄膜发射体优于Spindt发射体的特性。
Experimental measurements show the field emissioncurrent from actural field emitters is always much larger than that calculated from Fowler-Nordheimformula,It predicate that this idealized formula for actural field emitters should be modified,Thereasons for madifications and a rational quantitative method to medify this formula are given.
对场发射体的实验测量表明：实验结果往往比根据Ｆｏｗｌｅｒ－Ｎｏｒｄｈｅｉｍ公式计算的结果大得很多，说明这一理想化了的公式应用于实际场发射体时，必需得到修正。
Standard emitters are conventionally high-temperature cavity radiators.
标准发射体通常是高温辐射腔。
Hence a good absorber is a good emitter, and a poor absorber is a poor emitter.
所以良吸收体就是良发射体，劣吸收体就是劣发射体。
