EPJ B Colloquium - Why heavy doping makes ultrafast plasmonic semiconductors
- Published on 02 April 2013
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.
