Abstract :
A novel method of measuring high-speed electrical waveforms using a scanning tunneling microscope (STM) is demonstrated. An optical pulse train is used to turn on and off the photoconductive semiconductor switch (PCSS) on the STM probe to measure a high-speed signal in an equivalent sampling procedure. A temporal resolution of 160 ps has been achieved. This unique combination of optical sampling and STM technology is a breakthrough for measuring ultra-high-speed waveforms
