Molecular adsorption effects on excitons in air-suspended carbon nanotubes are investigated. Water adsorption induces excitonic energy shifts, giving rise to optical bistability which can be used for memory operations. Adsorption of organic phthalocyanine molecules provide strong screening and charge transfer, and decoration by pentacene modifies single-photon emission by forming local potentials.

摘要

Molecular adsorption effects on excitons in air-suspended carbon nanotubes are investigated. Water adsorption induces excitonic energy shifts, giving rise to optical bistability which can be used for memory operations. Adsorption of organic phthalocyanine molecules provide strong screening and charge transfer, and decoration by pentacene modifies single-photon emission by forming local potentials.
