Defect‐Resistant Radiative Performance of m‐Plane Immiscible Al₁−xInxN Epitaxial Nanostructures for Deep‐Ultraviolet and Visible Polarized Light Emitters

Planar vacuum-fluorescent-display devices emitting polarized UV-C, blue, and green light are demonstrated using immiscible Al1−xInxN nanostructures grown in nonpolar m-directions. Despite the presence of high concentration of nonradiative recombination centers, the Al1−xInxN nanostructures emit polarized light with the luminescence lifetimes of 22–32 ps at 300 K. This defect-resistant radiative performance suggests supernormal localized characteristics of electron–hole pairs.
