MBE Growth and Characterization of InAlGaAs/GaAs Quantum Dots

InAlGaAs/GaAs quantum dots (QDs) are grown by molecular beam epitaxy and subsequently characterized to achieve emission $\lt 1\ \mu$m. Growth parameters are optimized to grow a new generation of homogeneous quaternary QDs with a PL FWHM of $\sim 60\ \mathrm{meV}$ and a surface density of $\gt10^{10} \mathrm{~cm}^{-2}$.
