Light induced coarsening of metal nanoparticles

Metal particle coarsening driven by light illumination of the supporting semiconducting substrate.

Углеродные наноструктуры на полупроводниковой подложке

The analytical expressions for the density of states and the occupation numbers are obtained for simple models of carbon nanostructures (graphene–boron nitride lateral heterostructure, decorated zigzag edges of semi-infinity graphene and graphene nanoribbons, and decorated carbyne). The main attention is placed to the strong-coupling regime of the nanostructures with a semiconducting substrate. The numerical estimations are given for the SiC substrate.

Impact of ultrathin dielectric spacers on SERS: energy transfer between polarized charges and plasmons

Ultra-thin (<10 nm) dielectric spacers provide adequate screening for energy transfer from plasmonic nanoparticles to polarization charges of the high permittivity semiconducting substrate.
