چکیده

Energy efficient lighting can be achieved by help of high efficiency light emitting diodes (LEDs). Substantial performance gains are feasible in the green – 500–555 nm – spectral region by implementing proper design of the active region. Here we analyze external quantum efficiency of high performing LED dies as a function of current and temperature in order to formulate relevant optimization rules. Among a large sample set we identify traits that clearly correlate with respective device performance.

Analysis of the Quantum Efficiency of GaInN/GaN Light Emitting Diodes

In an attempt to identify the performance limiting factors of green GaInN/GaN light emitting diodes (LEDs) we analyze a large number of LED dies fabricated from over 160 epitaxy runs covering the wavelength range from 390 – 580 nm on a quantitative scale of the emission power. As a function of drive current, we analyze the external quantum efficiency (EQE) with particular emphasis on the low cu...

Bluish-green semipolar GaInN/GaN light emitting diodes on {11̄01} GaN side facets

Bluish-green semipolar GaInN/GaN light emitting diodes were realized on the {11̄01} side facets of selectively grown GaN stripes with an on-wafer optical output power of 240μW@20mA for about 500 nm emission wavelength. Structural investigations using TEM, SEM, HRXRD and AFM could be related to the luminescence properties in PL and CL. The defect-related luminescence peaks at 3.3 eV and 3.41 eV, ...

Green light emitting diodes on a-plane GaN bulk substrates

We report the development of 520–540 nm green light emitting diodes LEDs grown along the nonpolar a axis of GaN. GaInN /GaN-based quantum well structures were grown in homoepitaxy on both, a-plane bulk GaN and a-plane GaN on r-plane sapphire. LEDs on GaN show higher, virtually dislocation-free crystalline quality and three times higher light output power when compared to those on r-plane sapphi...

Analysis of reverse tunnelling current in GaInN light-emitting diodes

The characteristics of the reverse leakage current of GaInN/GaN multiple quantum well light-emitting diodes (LEDs) are examined with various n-type GaN doping concentrations and interpreted by using a tunnelling current model. Changing the doping concentration of the n-type GaN influences the tunnelling probability of electrons into the conduction band and thus the reverse leakage current. Redu...
