Resonance Raman Scattering Studies of Gallium-Arsenide - Aluminum-Arsenide Superlattices
… LA phonons and quantized LO phonons in several GaAs-AlAs superlattices. The motivation for this work was to study the electronic structure and the electron-phonon interaction in these structures. The samples were not intentionally doped. The Raman spectra of optic phonons were usually taken at a …

Anderson localization of thermal phonons : anomalous heat conduction in disordered superlattices
… function of system size. Our numerical study of GaAs/AlAs superlattices with ErAs nanoparticles exhibits this thermal conductivity maximum, yielding quantitative agreement to experiments. We then generalize our elastic model to allow for the incorporation of finite-temperature effects. The …
