We review recent experimental studies on the lattice dynamical properties of novel semiconductor InN thin films. Most of the experimental results are concerned with Raman scattering as well as infrared spectroscopic studies. The emphasis is on the structure of Brillouin zone centre (Γ point) phonons in InN (including both the wurtzite and zinc blende structures), coupling between the electron excitation (plasmon) and the longitudinal optical phonon, disorder-activated modes, temperature- and pressure-dependences of the lattice vibration modes, micro-Raman imaging, and the lattice vibration in nitride alloys, superlattices, quantum wells, and quantum dots, etc. This article also presents some prospects on Raman scattering studies in the related materials and structures.
