Tuning light emission crossovers in atomic-scale aluminum plasmonic tunnel junctions
Yunxuan Zhu, Longji Cui, Mahdiyeh Abbasi +1
Atomic sized plasmonic tunnel junctions are of fundamental interest, with great promise as the smallest on-chip light sources in various optoelectronic applications. Several mechan…
Thousand-fold Increase in Plasmonic Light Emission via Combined Electronic and Optical Excitations
Longji Cui, Yunxuan Zhu, Peter Nordlander +2
Surface plasmon enhanced processes and hot-carrier dynamics in plasmonic nanostructures are of great fundamental interest to reveal light-matter interactions at the nanoscale. Usin…
Electrically Driven Hot-Carrier Generation and Above-threshold Light Emission in Plasmonic Tunnel Junctions
Longji Cui, Yunxuan Zhu, Mahdiyeh Abbasi +4
Above-threshold light emission from plasmonic tunnel junctions, when emitted photons have energies significantly higher than the energy scale of the incident electrons, has attract…
Ultrafast modulation of near-field heat transfer with tunable metamaterials
Longji Cui, Yong Huang, Ju Wang +1
We propose a mechanism of active near-field heat transfer modulation relying on externally tunable metamaterials. A large modulation effect is observed and can be explained by the…
