纳米制造.关键控制特性.第5-4部分:用电子能量损失光谱法(EELS)测量纳米材料的能带隙
IEC TS 62607-5-4:2022 specifies the measuring method of the band gap energy of a nanomaterial using electron energy loss data of transmission electron microscope.
The method specified in this document is applicable to semiconducting and insulating nanomaterials to estimate the band gap.
The measurement to get reliable data is performed under the consistent conditions of TEM observation and specimen thickness. The applicable measurement range of band gap energy is more than 2 eV.
