Nano tungsten needle is often used as a STM probe. And Most of the STM probes are nano tungsten needles. Wherein, nano tungsten needle is made of high-purity tungsten wire with good electrical conductivity and mechanical strength. According to the experts, STM (Scanning Tunneling Microscope) is different from XRD (X-Ray Diffraction), LEED (Low Energy Electron Diffraction) and other reciprocal space imaging using diffraction methods. STM can directly image the conductive sample in real space with atomic resolution, and has achieved…
