Wavelength-Selective control of Atomic Scale Au Contacts

Werner Brämer-Escamilla, Werner Brämer-Escamilla, Floralba Lopez +4

We demonstrate wavelength-selective control of atomic motion in a mechanically controllable Au break junction. Excitation at ${\lambda }_{\mathrm{form}}\simeq 530\mathrm{nm}$ drives gap closu…
