Vector beam generation from standing hollow GaN nanowire lasers on sapphire substrate
Masato Takiguchi, Sylvain Sergent, Benjamin Damilano +9
We fabricated GaN based hollow nanowires standing upright on a sapphire substrate by the sublimation method and found that they exhibit laser oscillation at room temperature. These…
Revealing topological phase in Pancharatnam-Berry metasurfaces using mesoscopic electrodynamics
Zhanjie Gao, Sandeep Golla, Rajath Sawant +6
Relying on the local orientation of nanostructures, Pancharatnam-Berry metasurfaces are currently enabling a new generation of polarization-sensitive optical devices. A systematica…
Origins of GaN(0 0 0 1) surface reconstructions
S. Vezian, F. Semond, J. Massies +3
The reconstructions of the Ga polarity GaN(0 0 0 1) surface with and without trace amounts of arsenic and prepared by molecular beam epitaxy (MBE) have been studied with in situ re…
The role of magnetic polarons in ferromagnetic GdN
Franck Natali, Ben Ruck, Joe Trodahl +6
We report an interplay between magnetism and charge transport in the ferromagnetic semiconductor GdN, pointing to the formation of magnetic polarons centred on nitrogen vacancies.…
