Active plasmonic mode guiding in semiconductor Schottky nanostructures

Plasmonics bring hopes to overcome the bandwidth limitation in interconnectors in integrated electronic circuits, which are not capable to cater the demand for high data bandwidths in the years to come. This study investigates the light propagation in Schottky junction based nanostructures to achieve lossless plasmonic waveguides. The thesis presents analytical explanations and numerical simulations of plasmonic mode guiding in various metal-semiconductor nanostructures by incorporating an amplification scheme to improve the mode propagation length and mode confinement. The proposed techniques will largely assist in designing low-loss plasmonic interconnects for integrated nanocircuits and highly sensitive compact plasmonic sensing devices.
