LED07 – Effect of Parabolic Quantum Well on Internal Quantum Efficiency of InGaN/GaN based MicroLED at low current density

Gurjar R., Prakash Singh C., Singh Meena A., Ghosh K.

The quantum cascade stark effect (QCSE) in rectangular shaped quantum well (QW) poses a hindrance to increase the internal quantum efficiency (IQE) of nitride based LEDs. To circumvent the said problem for micro-LEDs operating at low current density, a parabolic QW structure has been proposed which is found to be useful to alleviate the QCSE […]
