英文摘要
We studied the temperature dependence of the dielectric dispersion of SrTiO3 thin films on MgAl2O4 by broadband THz-TDS and we found evidence of a ferroelectric phase transition at around 170 K. Furthermore, the increase ofε" in the gigahertz frequency region and the increase ofγTO1 below T_c imply the existence of polar nanoregions that have been observed in other ferroelectric materials with a perovskite structure and relaxor ferroelectrics.
