Outline of Final Research Achievements |
In this study, the work function of metal nanoparticle was quantitatively measured by using of scanning probe microscopy. By exchanging the capping organic molecules of silver and gold nanoparticles, their work functions were successfully tuned in the range of about 1.00 eV. The effect of light incident on the work function was also studied. The mechanism between plasmon and work function was discussed. In the future, the metal nanoparticles with tunable work functions are expected for the nano devices.
