SEM方面:(EDS作为SEM的一个配件,EDX的探头伸进SEM的真空腔内) 加速电压HV/EHT:通常需要有一个过压比,即加速电压必须大于特征X谱线能量,通常是2~3 倍;对于轻元素,比如F,C等,一般用5KV,而对于金属元素则需要20KV; 探针电流/束流/束斑尺寸(SpotSize / Beam Current):让灯丝处于饱和状态以获得稳定的束流; 光...
Energy-dispersive X-ray spectroscopy (EDS, also abbreviated EDX or XEDS) is an analytical technique that enables the chemical characterization/elemental analysis of materials. A sample excited by an energy source (such as the electron beam of an electron microscope) dissipates some of the absorbed...
