“…. then the sweep was reversed back to 0.1 V. As we shall discuss in greater detail below this curve looks qualitatively like the curve reported by several groups [9,17,18] for Au(l11), but the "flat-bottom" minimum in the capacity at 0.45 -0.6 V is not seen on Au(111). The curve 5 in Figure 1 was quite stable to repeated cycling between these potentials.…”

“…In the case of gold, particular care should be taken to control the nature of the surface structure since this can be easily altered by the surface reconstruction phenomena [7,17]. For gold and silver, a lot of information has been gathered about the influence of the surface structure [17][18][19][20][21], specific adsorption and temperature [22][23][24][25][26][27] on the potential of zero charge.…”

Abstract.The determination of the potentials of zero total and free charge, pztc and pzfc respectively, were made in a wide pH range by using the CO displacement method and the same calculation assumptions used previously for Pt(111) electrodes in contact with nonspecifically adsorbing anions. Calculation of the pzfc involves, in occasions, long extrapolations that lead us to the introduction of the concept of potential of zero extrapolated charge (pzec). It was observed that the pztc changes with pH but the pzec is independent of this parameter. It was observed that the pztc>pzec at pH > 3.4 but the opposite is true for pH>3.4. At the latter pH both pzec and pztc coincide. This defines two different pH regions and means that adsorbed hydrogen has to be corrected in the "acidic" solutions at the pztc while adsorbed OH is the species to be corrected in the "alkaline" range. The comparison of the overall picture suggests that neutral conditions at the interface are attained at significantly acidic solutions than those at the bulk.

“…The work function of a single crystalline gold is typically around 5 eV. [27][28][29][30] For the few-cycle laser pulse with a photon energy of 1.65 eV, at least four photons are needed to eject an electron into the continuum. The laser intensity is varied using a variable neutral density (ND) filter, where scanning the variable ND filter does not produce a detectable change in pulse duration or CEP.…”

Extreme nonlinear terahertz electro-optics in diamond for ultrafast pulse switching APL Photonics 2, 036106 (2017) Metal nanotip photoemitters have proven to be versatile in fundamental nanoplasmonics research and applications, including, e.g., the generation of ultrafast electron pulses, the adiabatic focusing of plasmons, and as light-triggered electron sources for microscopy. Here, we report the generation of high energy photoelectrons (up to 160 eV) in photoemission from single-crystalline nanowire tips in few-cycle, 750-nm laser fields at peak intensities of (2-7.3) × 10 12 W/cm 2 . Recording the carrier-envelope phase (CEP)-dependent photoemission from the nanowire tips allows us to identify rescattering contributions and also permits us to determine the high-energy cutoff of the electron spectra as a function of laser intensity. So far these types of experiments from metal nanotips have been limited to an emission regime with less than one electron per pulse. We detect up to 13 e/shot and given the limited detection efficiency, we expect up to a few ten times more electrons being emitted from the nanowire. Within the investigated intensity range, we find linear scaling of cutoff energies. The nonlinear scaling of electron count rates is consistent with tunneling photoemission occurring in the absence of significant charge interaction. The high electron energy gain is attributed to field-induced rescattering in the enhanced nanolocalized fields at the wires apex, where a strong CEP-modulation is indicative of the attosecond control of photoemission. © 2017 Author(s)
