Superior Optoelectronic Performance of N-Polar GaN LED to Ga-Polar Counterpart in the “Green Gap” Range
The low luminous efficiency of indium gallium nitride (InGaN) light-emitting diodes (LED) in the “green gap” range has been a long unsettled issue confounding the researchers.One of the main obstacles comes from the intrinsic polarization field in the incumbent Body Massage Tool Ga-polar LEDs (Ga-LEDs), where the polarization field wi
