Heterodyne x-ray diffuse scattering from coherent phonons
Here, we report Fourier-transform inelastic x-ray scattering measurements of photoexcited GaAs with embedded ErAs nanoparticles. We observe temporal oscillations in the x-ray scattering intensity, which we attribute to inelastic scattering from coherent acoustic phonons. Unlike in thermal equilibrium, where inelastic x-ray scattering is proportional to the phonon occupation, we show that the sc...
متن کاملX-Ray Diffuse Scattering
In this research program, modern x-ray scattering techniques are used to study the structures and phase transitions in novel states of condensed matter. We have two principal experimental facilities. At M.I.T. we have three high-resolution computer controlled x-ray spectrometers using either a conventional or high intensity rotating anode x-ray generator. The angular resolution can be made as f...

متن کاملDiffuse X-ray scattering of amorphous multilayers
We present a new method to measure the difuse scattering of amorphous multilayers. In contrast to conventional scans, that all take place in the plane of reflection, in this out-of-plane scattering geometry the accessible range in parallel momentum transfer Qi is not limited by the sample surface. We can therefore record data continuously from
