We have designed and built an optical system to collect light that is generated in the tunneling region of a low-temperature scanning tunneling microscope. The optical system consists of an in situ lens placed approximately 1.5 cm from the tunneling region and an ex situ optical lens system to analyze the emitted light, for instance, by directing the light into a spectrometer. As a demonstration, we measured tip induced photoluminescence spectra of a gold surface. Furthermore, we demonstrate that we can simultaneously record scanning tunneling microscope induced luminescence and topography of the surface both with atomic resolution.
我们设计并构建了一个光学系统，用于收集在低温扫描隧道显微镜的隧穿区域产生的光。该光学系统由一个距隧穿区域约1.5厘米放置的原位透镜和一个用于分析发射光的非原位光学透镜系统组成，例如，通过将光导入光谱仪来进行分析。作为演示，我们测量了金表面的针尖诱导光致发光光谱。此外，我们证明了我们能够以原子分辨率同时记录扫描隧道显微镜诱导的发光和表面形貌。
