Abstract:

Using time-resolved x-ray diffraction ultafast lattice dynamics in fs-laser-excited crystalline bulk Ge and Ge/Si-heterostructures has been studied. This experimental technique uniquely allows us to observe fast energy transport deep into the bulk of the material, coherent acoustic phonon dynamics, lattice anharmonicity, and vibrational transport across a buried interface.
