Controlling the dopant profile for SRH suppression at low current densities in 1330nm GaInAsP light-emitting diodes
Parthiban Santhanam, Wei Li, Bo Zhao +5
The quantum efficiency of double hetero-junction light-emitting diodes (LEDs) can be significantly enhanced at low current density by tailoring the spatial profile of dopants to su…
