EPJ B Colloquium - Why heavy doping makes ultrafast plasmonic semiconductors

This EPJB Colloquium reviews the pioneering studies of plasmon resonance in heavily doped semiconductor thin films. It also reports the chemical synthesis and structural properties of heavily doped semiconductor nanocrystals. Their linear plasmonic response (under excitation with weak continuous-wave optical fields) is illustrated both theoretically and experimentally. Finally, the authors review the most recent results on the transient (i.e. nonlinear) ultrafast plasmonic features exhibited by chalcogenide nanocrystals under excitation with ultra-fast optical pulses, including a “gold-like” theoretical model. This model turns out to provide sufficient insights into the first experiments on heavily-doped plasmonic nanoparticles.
