Multi Quantum Well

Optical properties of green emission Ga 0.80 In 0.20 N/GaN multi-quantum well and light emitting diode have been investigated by using photoluminescence, cathodoluminescence, electroluminescence, and photoconductivity. The temperature dependent photoluminescence and cathodoluminescence studies show three emission bands including GaInN/GaN quantum well emission centered at 2.38 eV (~ 520 nm). The activation energy of the non-radiative recombination centers was found to be ~ 60 meV. The comparison of photoconductivity with luminescence spectroscopy revealed that optical properties of quantum well layers are strongly affected by the quantum-confined Stark effect.

Charge transport has been simulated in a novel two quantum well InGaN/GaN light emitting diode. Asymmetric tunnelling for holes and electrons has been used to enhance the quantum efficiency of the diode. A self-consistent solution of Poisson and Schrödinger equations has been used to obtain the band profile, energy levels and wave functions. Transport in the bulk nitride has been simulated by a drift diffusion model. Lattice strain and the resulting piezoelectric field effects have been shown to influence the device characteristics.
