A PLASMON GENERATOR

摘要

A plasmon generator comprises a plasmon supporting surface and first and second quantum systems respectively defining first and second quantum states with a tunneling junction being present between the first and second quantum systems, the first and second quantum systems being present in an electric circuit to generate a tunneling current between the first and second quantum systems, whereby electrons tunneling between said first and second quantum states loose energy in the process and generate plasmons at the plasmon supporting surface.
