Abstract
The atomic intermixing of In x Ga 1-x As/InP quantum well structures induced by arsenic irradiation has been investigated using photoluminescence (PL) measurement. The ion doses used were varried from 5x10 11 As/cm 2 to 1x10 13 As/cm 2 . Also, the irradiation temperature were carried out from -200 o C to 300 o C. The samples were annealed under Argon flow in rapid thermal annealer (RTA) at 750 o C for 60 second. The photoluminescence result showed that there was increase in energy shift at lower doses. However, the energy shift was saturated at higher dose. At elevated temperature implantation showed that the energy shift did not change significantly for all the samples (LM, TS, CS). In additon to this, the higher energy shift was observed in the Compressive Strain (CS) samples, but the lower of the energy shift was experienced in the Tensile Strain (TS) samples.
