Polarization Enhancement and Resonance Tuning Inferred From Theoretical Consideration and Numerical Simulation for a Semiconductor Nanoparticle With a Dielectric Shell

Electric polarizations in metallic nanoparticles have enabled them to be employed in a variety of applications such as sensors, light trapping, polarizer, filter, and wave guiding at optical frequencies. Semiconductor nanoparticles, with a lower carrier concentration and hence plasma frequency, can...
