Using a bismuth-doped aluminosilicate fibre laser tunable in the range 1130–1210 nm, we have examined the effect of pump wavelength on the gain spectrum of bismuth-doped phosphosilicate fibres in the range 1220–1400 nm. At a pump wavelength of 11

The dynamics of excited electrons in insulator quantum well states on a metal substrate were determined by femtosecond two-photon photoemission for the first time. Lifetimes are reported for the first three excited states for 1{endash}6 atomic layers

▪ Abstract Two-photon photoemission is a promising new technique that has been developed for the study of electron dynamics at interfaces. A femtosecond laser is used to both create an excited electronic distribution at the surface and eject the di

The energies and dispersions of the image states and quantum well electronic states in layers of Xe and Kr on a Ag(111) substrate were determined by angle‐resolved two‐photon photoemission (ARTPPE). For Xe, we measured binding energies of unoccup

Femtosecond time-resolved two-photon photoemission spectrocopy (TPPE) has been used to measure the lifetimes of image potential electrons at alkane mono- and bilayers on Ag(111). The n = 1 lifetimes for zero, one, and two layers of n-heptane on Ag(11

Evidence for electron localization in 2D at metal-dielectric interfaces is reported. A nondispersive peak, derived from the image-potential state and observed in angle-resolved two-photon photoemission, is assigned to localized excess electrons. The

Operation of 40 Gb/s mesh networks with reconfigurable add-drop multiplexing leads to the need for dispersion maps that support flexible traffic routing. We use transmission simulations to determine dispersion maps with optimum performance and routin

The dynamics of two-dimensional small-polaron formation at ultrathin alkane layers on a silver(111) surface have been studied with femtosecond time- and angle-resolved two-photon photoemission spectroscopy. Optical excitation creates interfacial elec

Angle resolved two-photon photoemission (TPPE) spectroscopy has shown that the energies and effective masses of image potential electrons outside metal surfaces are very sensitive to the morphology and electronic structure of atomically thin adlayers

Using angle-resolved two-photon photoemission with femtosecond time resolution, it is possible to measure many dynamical properties of electrons in 2-D systems, including tunneling, localization, and momentum scattering.
