Photoluminescence Of Indium Gallium Arsenide Quantum Dots And Dot Chains

Nanostructures such as quantum dots (QDs) and QD chains have received signirn cant attention because of their applications in quantum information technologies.rnThis paper presents optical investigations of InGaAs QDs and dotrnchains. The InGaAs samples were grown on a (001) GaAs substrate by Dr.rnHaeyeon Yang using a novel method similar to the Stranski-Krastonov growthrnmethod. Intensity and temperature dependence of the sample photoluminescencern(PL) spectra were obtained through optical excitation and detection.rnThe presence of a PL peak at 1 m suggests the successful creation of QDrnchains. Also outlined is the method for calculating the PL curve-correctingrnfunctions to account for grating e ciencies and a changing reciprocal linearrndispersion in monochromators.
