Qısa məlumat

The temperature dependence of the elastic coefficients of T1InS2 has been investigated by Brillouin scattering measurements. For longitudinal phonons propagating in the (001) plane the variation of ΔC∼∼(Tc-T) was found below the ferroelectric transition point (Tc=189 K). For propagation perpendicular to the (001) plane (C33 mode) clear anomalies were observed at T=213 K and T=195 K. Between these temperatures the Brillouin peaks show broadening, which is attibuted to a coupling between the acoustic mode and an overdamped mode. © 1987.
