太赫兹近场光学显微镜 — THz-NeaSNOM参数指标

参数指标我要纠错

THz-NeaSNOM主要技术参数与特点:

 

     THz-NeaSNOM近场光学显微镜(下图左)对半导体结构的测量结果图。该结果表明硅衬底(上图左,灰色)上的SiO(一氧化硅)的尺寸大约在1.5×1 平 方微米。通过分析左侧的高度数据,可以知道该一氧化硅结构仅仅只有大约22纳米厚度。虽然该层状结构非常薄,但THz-NeaSNOM近场光学显微镜(下图左)在测量高度的同时仍然能够记录该结构与衬底的近场光学信号的明显不同衬度的结果。该THz-NeaSNOM近场光学显微镜不仅在测量非常薄样品的时 候灵敏度非常高,而且通过分析近场光学信号数据(下图右)也证实了它超高的空间分辨率(~25-30nm)。
