Electron-Energy Dependent Excitation and Directional Far-Field Radiation of Resonant Mie Modes in Single Si Nanospheres
{{output}}
High-energy electron beams with energies in the 15-30 keV range are used to excite optical Mie modes in crystalline Si nanospheres with radius 80-100 nm. Cathodoluminescence (CL) spectra show emission from resonant electric and magnetic dipole and quadrupole m... ...
