Electronic structure of indium phosphide clusters: anion
نویسندگان
چکیده
Ž . Photoelectron spectra for indium phosphide InP cluster anions comprised of up to 27 atoms were measured at a photodetachment wavelength of 266 nm. Results are presented for cluster anions of both stoichiometric and non-stoichiometŽ y y . Ž . ric composition In P , In P ; xs1–13 . In P exhibits the lowest electron affinity EA of all the clusters studied, x x xq1 x 3 3 indicating a particularly stable neutral species. The EAs of the stoichiometric clusters are considerably lower than those of the corresponding non-stoichiometric clusters, suggesting the presence of closed-shell ground states for the neutral In P x x clusters. Remarkable agreement between the experimental EAs and those derived from calculations on quantum dots is found. q 1999 Elsevier Science B.V. All rights reserved.

Nano cavities based on silicon and indium phosphide materials have been comparedin this study, considering field intensity enhancement factor. The results of FDTD based simulations declare that the Si nano-cavity improves confined optical field about 7.7 times higher than the InP based nano-cavity. The introduced dielectric nano-cavities support resonance wavelength at about λ=1.55 μm.
