We report on the photoluminescence (PL) properties of InAs/InAlAs/InP quantum wires (QWRs) with various InAs deposited thickness. The PL linewidth of the QWRs decreases with increasing InAs deposited thickness due to the different thicknesses of the QWRs and defects in the samples. The defects and lateral composition modulation of the InAlAs layers play an important role in the temperature-dependent...
We have studied the effect of the post-growth rapid thermal annealing on optical and electrical properties of InAs/InAlAs/InP quantum wires with various InAs deposited thickness. Quite different annealing behaviors in photoluminescence and dark resistance are observed, which can be attributed to dislocations in samples. After annealing at 800°C, quantum wires still exist in the sample with two monolayer...
