Dipole moment of nanoparticles at interfaces
1999 (English)In: Physical Review Letters, ISSN 0031-9007, Vol. 83, no 2, 380-383 p.Article in journal (Refereed) Published
The properties of heterogeneous interfaces are modified essentially by the presence of nanoparticles. We provide a model and give spectroscopic evidence that nanoscale clusters exist which have a metallic core and a shell of an almost perfect oxide. Such clusters produce a large dipole moment which manifests itself as shifts in core levels as seen by photoelectron spectroscopy, as well as non-Ohmic rectifying behavior in the device electrical properties.
