Structural phase transitions in relaxor ferroelectric materials remain to be one of the most puzzling issues in solid-state physics. In the present work, we have investigated relaxational and vibrational properties of a relaxor ferroelectric 0.71Pb(Ni<sub>1/3</sub>Nb<sub>2/3</sub>)O<sub>3</sub>-0.29PbTiO<sub>3</sub> single crystal by means of inelastic(More)
Abstract-Structural phase transitions in relaxor ferroelectric materials remain to be one of the most puzzling issues in materials science. In the present work, we have investigated relaxational and vibrational properties of a relaxor ferroelectric 0.71Pb(Ni(1/3)Nb(2/3))O(3)-O.29PbTiO(3) single crystal by means of inelastic light scattering measurements.(More)
Difficulty to achieve high density FeRAMs with sub-micron ferroelectric capacitors is widely understood due to damage to the capacitors. Key process techniques such as high quality ferroelectric film deposition, electrode preparation, capacitor RIE and hydrogen barrier structure formation are introduced for 64M FeRAMs with sub micron high reliability PZT(More)
