Allotropic Ga${}_2$Se${}_3$/GaSe nanostructures grown by van der Waals epitaxy: Narrow exciton lines and single-photon emission

Maxim Rakhlin, Sergey Sorokin, Aidar Galimov +5

The ability to emit narrow exciton lines, preferably with a clearly defined polarization, is one of the key conditions for the use of nanostructures based on III-VI monochalcogenid…
