Simplified method for fabricating single-contact nano-LEDs using AC instead of DC power, for AR/ VR headsets/ smart glasses

"DC-powered LEDs require 2 contacts (p, n) causing alignment/ fabrication challenges as device sizes shrink to nanoscale, overcome using AC requiring only 1... 300 nm thick nanorods for high pixel densities... electrons to photons conversion (quantum efficiency) controls AC current frequency tuning by the manufacturer, enabling visible flicker elimination while maintaining efficient light generation... also: optical communications, biomedical devices... more efficient nanoscale LED devices"
