Mapping local optical densities of states in silicon photonic structures with nanoscale electron spectroscopy
Mapping local optical densities silicon photonic structures nanoscale electron spectroscopy
2015/8/10
Relativistic electrons in a structured medium generate radiative losses such as Cherenkov and transition radiation that act as a virtual light source, coupling to the photonic densities of states. The...
