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