Raman scattering in chalcogenide-based ferroelectrics: from bulk to nanoscale

Evolution of Raman spectra of Sn2P2S6 and SbSI ferroelectrics is traced with the size reduction from bulk to nanometric crystals by milling. The role of confinement‐related selection rules relaxation and surface phonon modes in the observed Ranam line broadening and asymmetry is discussed. (© 2004 W...
