Analysis of materials properties of thin film structures for thermoelectric and thermophotovoltaic applications
… was used to grow InAsP graded layers and AlAs/GaAs superlattices for materials studies related to thermophotovoltaics and thermoelectrics respectively. High resolution x-ray diffraction (HRXRD) was used to determine the As concentration in each of the InAsP layers. Arsenic concentration was …

Study of phonon transmission through solid-solid interfaces and superlattices by phonon imaging
… interface. 3. Phonon transmission through superlattices. Phonon imaging experiments on several InxGa""xAs/A1As and A1As/GaAs superlattices examine the angular distribution of high-frequency acoustic phonon transmission through periodic superlattices. Bragg reflection of phonons is studied …

Brillouin scattering from opaque semiconducting alloys and thin films
… films of A1xGal_xAs alloys and AlxGal_xAs -GaAs supedattices on GaAs substrates, and GaAs films grown on miscut Si substrates. To detect the Brillouin shifted light against the strong elastic background present in opaque materials, a tandem multipass Fabry-Perot system was designed and …
