Evidence for parallel confinement in resonant charge transfer of negative hydrogen ion near metal surfaces
Himadri S. Chakraborty, Thomas Niederhausen, Uwe thumm
Using a wave packet propagation approach, we find that the resonant charge transfer process of H^- near a Cu(111) surface is strongly influenced by transient hybrid states. These s…

Oscillations in the photocurrent from quantum dots: Geometric information from reciprocal spectra
Himadri S. Chakraborty, Rashid G. Nazmitdinov, Mohamed E. Madjet +1
We demonstrate that the current of photoelectrons from a quantum dot exhibits oscillations as a function of the photon energy owing to the predominant ionization from the dot bound…

Energetic photoionization of neutral and ionic metal clusters
Himadri S. Chakraborty, M. E. Madjet
We show, with an example of Na_92, that for jellium metal clusters the interference of fast electron-waves emitted from equivalent sites on the cluster edge produces monochromatic…
