Phonons in Crystals using Inelastic X-Ray Scattering

The use of inelastic x-ray scattering (IXS) to investigate phonons and phonon dispersion in crystals opens the field of phonon spectroscopy, allowing measurements on tiny samples: micrograms of material, or single crystals ~10 to 100 micron diameter are sufficient. Here we review the technique as it is practiced at BL35XU of SPring-8, in Hyogo prefecture. An introduction is provided that is aimed at potential IXS users, highlighting the unique and advantageous aspects of the technique. Present work, including several example experiments, and future directions are discussed.
