    Abstract

    Confined acoustic phonons in Silicon‐on‐insulator membranes have been observed by means of low frequency Raman scattering. The dependence of the Raman peak frequencies and amplitudes upon the thickness of the silicon membrane is interpreted as acoustic phonons in an acoustic cavity. The analysis confirms that these acoustic phonons are confined.
