Abstract

Calculations are done and compared for two AlGaInP single- quantum-well (SQW) LED structures: step separate- confinement-heterostructure (SCH) SQW structure and graded- index (GRIN) SCH-SQW structure. It is found that the latter has better performance in terms of spontaneous lifetime and injection efficiency. This is attributed to greater barrier height to electron leakage and substantial overlap between wavefunctions of different quantum numbers in the GRIN-SCH- SQW structure. Results also show that the GRIN layer thickness has no influence on the QW energy levels. spontaneous lifetime and injection efficiency in a GRIN-SCH- SQW.
