Abstract
The recent discovery that metal nanoparticles can generate hot carriers upon light excitation is seen as a breakthrough in the fields of plasmonics and photonics. However, the high expectations for...
Highlights
Nanostructures have a high density of free charge carriers and can concentrate incoming light to volumes much smaller than the diffraction limit
This outstanding phenomenon is a consequence of coherent oscillations of free electrons in a metal nanoparticle driven by the external electromagnetic waves commonly referred as localized surface plasmon resonance (LSPR) or localized surface plasmon polariton resonance
The LSPR decays transferring the energy to form energetic electron−hole pairs in the femtosecond time scale known as hot carriers,[16] a discovery seen as a breakthrough in the fields of plasmonics and photonics.[17]
Summary
Nanostructures have a high density of free charge carriers and can concentrate incoming light to volumes much smaller than the diffraction limit. The higher Fermi level position of AZO80 in comparison to ZnO can be used to explain the lower injection efficiency observed in the former
