Polariton Bose-Einstein condensate at room temperature in a Al(Ga)N nanowire-dielectric microcavity with a spatial potential trap

open access: yes, 2012
A spatial potential trap is formed in a 6.0 {\mu}m Al(Ga)N nanowire by varying the Al composition along its length during epitaxial growth. The polariton emission characteristics of a dielectric microcavity with the single nanowire embedded in-plane has ...

Current Collapse-Free and Self-Heating Performances in Normally Off GaN Nanowire GAA-MOSFETs

open access: yesIEEE Journal of the Electron Devices Society, 2018
Normally off lateral GaN nanowire gate-all-around MOSFETs have been fabricated on the GaN-on-insulator substrate. The dynamic measurement proved that the devices with various nanowire heights exhibit current collapse-free characteristics implying that ...

Tailoring the Geometry of Bottom-Up Nanowires: Application to High Efficiency Single Photon Sources

open access: yesNanomaterials, 2021
For nanowire-based sources of non-classical light, the rate at which photons are generated and the ability to efficiently collect them are determined by the nanowire geometry.

Superconducting Vortices induced Periodic Magnetoresistance Oscillations in Single Crystal Au Nanowires

open access: yes, 2011
We show in this paper that it is possible to induce superconducting vortices in a gold nanowire connected to superconducting electrodes. The gold nanowire acquires superconductivity by the proximity effect.
