Sampling measurements of electrical transients generated photoconductively on a 5-μm gold coplanar transmission line on GaAs were performed via multiphoton photoemission. A temporal resolution of 5 ps was achieved, with a voltage sensitivity of 10 mV/(Hz)1/2. These results confirm that the temporal resolution attainable by this technique is enhanced when the dimensions of the structure under examination are reduced.

    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 =...

    A phenomenological approach is presented that allows one to model, and thereby interpret photoemission spectra of strongly correlated electron systems. A simple analytical formula for the self-energy is proposed. This self-energy describes both the coherent and incoherent parts of the spectrum...

    We describe the fabrication and operation of a device which performs linear optical up-conversion at room temperature. The mechanism for up-conversion is based on internal photoemission from a Schottky contact. We then describe the voltage dependence of this device and interpret it in terms of...
