Ultrafast electron dynamics in silver nanoparticle arrays

Ultrafast electron dynamics in silver nanoparticle arrays

We present the results of ultrafast optical experiments on silver quantum dot super-lattices. Dramatic changes in the electron dynamics occur as a function of interparticle spacing due to enhanced dipolar coupling and, most importantly, electron delocalization.
