When stacking quantum wires yields polarized LEDs

In their quest for the manufacture of efficient polarized microLEDs, a team of researchers from the University College of Cork, Ireland, have turned their attention to highly anisotropic wire-like nanostructures, which could combine good carrier confinement with a highly anisotropic structure, yielding a strong light emission anisotropy. Their paper titled "Three-Dimensional Self-Assembled Columnar Arrays of AlInP Quantum Wires for Polarized Micrometer-Sized Amber Light Emitting Diodes" reviews prior art strategies in the optimization of carrier confinement.
