Electrochemical Potentiostatic Activation for the Improvement of 270 nm AlGaN-Based UV-C Light-Emitting Diodes

The electrochemical potentiostatic activation (EPA) method was performed by removing hydrogen atoms from the inside of the Mg-doped p -GaN/ p -AlGaN multilayer of 270 nm AlGaN-based UV-C light-emitting diodes (UV-C LEDs). The EPA evaluation was controlled among the applied voltages of 2, 3, and 4 V...
