【 摘 要 】

To study time-resolved photoemission from gold nanospheres, we introduce a semi-analytical quantum- mechanical model, including the plasmonic near-field-enhancement of the streaking field at the surface of the nanosphere. For an 800 nm incident near infrared (NIR) pulse and 10 nm diameter gold nanosphere, we find that the presence of the nanoplasmonic field enhances the oscillation amplitude by a factor of 3.
