The paper reviews applications of ABC-model to interpret internal quantum efficiency and its
droop in III-nitride light-emitting diodes. Advantages of the model, its intrinsic limitations, and …

Significant progress has been made in the advancement of light-emitting devices in both the
blue and the red parts of the emission spectrum. However, the quantum efficiency of green …

GaN-based micro light-emitting diode (μLED) arrays are very promising devices for display
applications. In these arrays, each μLED works as a single pixel of a whole image. The …

Physical mechanisms causing the efficiency droop in InGaN/GaN blue light-emitting diodes
and remedies proposed for droop mitigation are classified and reviewed. Droop …

The realization of the first high-brightness blue-light-emitting diodes (LEDs) in 1993 sparked
a more than twenty-year period of intensive research to improve their efficiency. Solutions to …

A droop-free nitride light-emitting diode (LED) with the capacity to operate beyond the
“green gap” has been a subject of intense scientific and engineering interest. While several …

For accurate and reliable measurement of the internal quantum efficiency (IQE) of light-
emitting diodes (LEDs), the method should be theoretically solid and experimentally simple …

The potential of multicolor semiconductor electroluminescence in solid-state lighting has
been extensively pursued due to the energy-saving and smart-lighting as compared to …

We investigate the current-dependent and temperature-dependent efficiency droops (" J-
droop" and" T-droop", respectively) in InGaN-based blue and AlGaInP-based red light …

Room‐temperature‐high‐efficiency light‐emitting diodes based on metal halide perovskite
FAPbI3 are shown to be able to work perfectly at low temperatures. A peak external quantum …
