Artistic representation of the alloyed Si1?xGex
nanoparticles with 4-ATP molecules adsorbed on their surface. Isolated
Mie nanoresonator is pumped with laser radiation resulting in SERS
from the attached molecules as well as Stokes Raman yield related to
Si1?xGex lattice phonons, which provides information on the local
temperature of the molecule-nanoantenna system and corresponding
spatial position the nanoresonator.
