Impact of mesh-like top p-electrode on output performance of light-emitting diode: Numerical study

Numerical model and procedure for the light-emitting diode (LED) with realistic mesh strips having square cross-section are developed and used for simulation of electrical and output optical characteristics at different dimensions of the mesh and bias voltages. Performances simulated for realistic square cross-section strips and analytical model based on the finite-radius wire approximation were compared. Comparison demonstrates the advantages of realistic model, in particular, for extraction of the mesh-like electrode parameters resulting in maximum optical output.
