ABSTRACT
We propose and demonstrate a new method for contactless sampling of high-speed electrical signals, by spectral analysis of photoelectrons emitted when a signal-carrying conductor is illuminated by ultrashort light pulses. We present time-resolved measurements of sub-ns electrical signals on a gold transmission line on GaAs using three-photon photoemission induced by 80 fs visible laser pulses, and we discuss the temporal resolution of these measurements. This method is applicable to devices and circuits on any semiconductor.

    Abstract. The STM can be used to investigate lifetimes of hot holes in a surface state at low temperatures. We analysed dI/dV data from Ag(111) using detailed tunnelling calculations and a simple model and found an electron self-energy of SIGMA = 4.9 +/- 0.6 meV. The corresponding lifetime tau =...
