Photoelectric emission and work function of semiconducting diamonds

Ultrafast Time-Resolved Photoelectric Emission.

The emission times of laser-triggered electrons from a sharp tungsten tip are directly characterized under ultrafast, near-infrared laser excitation at Keldysh parameters of 6.6<γ<19.1. Emission delays up to 10 fs are observed, which are inferred from the energy gain of photoelectrons emitted into a synchronously driven microwave cavity. Few femtosecond timing resolution is achieved in a config...

Intensity formula for optical emission and photoelectric effect

In this paper different methods supporting a new intensity formula in optical emission spectroscopy are presented. Three independent experimental and analytical methods have been developed which strongly support this new formula. Different light sources have also been used in this work. A new theory has earlier also been presented which strongly verify the new formula. Support is also given fro...

Photoelectric emission from the alkali metal doped vacuum-ice interface.

The photoelectron photoemission spectra and thresholds for low coverages of Li and K adsorbed on water-ice have been measured, compared with photoionization spectra of the gas-phase atoms, and modeled by quantum chemical calculations. For both alkali metals the threshold for photoemission is dramatically decreased and the cross section increased on adsorption to the water-ice surface. Quantum c...
