| 摘 要： | 根据对内全反射(TIR)棱镜表面成指数衰减规律倏逝场的检测和分析,本文叙述了一种新型的光子扫描隧道显微技术(PSTM),被分析的样品置于棱镜表面,它空间调制了上述倏逝场。通过对被调制倏逝场的检测获得了远小于光波波长的空间分辩能力.PSTM实验系统中使用了633nm 的 He-Ne 激光,用直径约300nm 的光纤探针对不同薄膜样品进行检测,其结果与光隧道理论相符。

| Abstract: | This paper presents a new form of scanning optical microscopy,the photon scanning tunneling microscopy (PSTM),which is based on the detection and analysis of the exponentially decaying evanescent field generated by total internal reflection (TIR) lying on the surface of the prism.The sample which is placed or coated on the surface of the prism spatially modulates the evanescent field.It may lead to subwavelenyth resolution in three dimensions.An experimental PSTM system is set up by using 633nm laser light and about 300nm-diameter probe tip.Experiment results are obtained in different thin film samples and have proved the agreement with photon tunneling theory. |
