Ultra Wide Range Dielectric Spectroscopy of Strontium Titanate-Strontium Zirconate Solid Solution

Dielectric Strontium Zirconate Sprayed by a Plasma Torch

Amultifunctional material, strontium zirconate, SrZrO3, studied in literatures as a dielectric ceramics, thermal barrier coating, proton-conductor, and luminescent material was sprayed by a water-stabilized plasma torch WSP 500. Stainless steel and plain carbon steel were used as substrates. Coatings with thickness of 1 to 2 mm were produced, whereas the substrates were preheated over 450 °C. T...

Persistent photoconductivity in strontium titanate.

Persistent photoconductivity was observed in strontium titanate (SrTiO(3)) single crystals. When exposed to sub-bandgap light (2.9 eV or higher) at room temperature, the free-electron concentration increases by over 2 orders of magnitude. After the light is turned off, the enhanced conductivity persists for several days, with negligible decay. From positron lifetime measurements, the persistent...

Phase Transitions in Strontium Titanate

Strontium Titanate SrTiO3 (STO) is known to undergo an antiferrodistortive transition from cubic to tetragonal phase at Tc ≈ 105K, and classical to quantum paraelectric phase transition at Tq ≈ 37K. This paper is intended to use Landau Theory to explore these two phase transitions of STO, as well as some experimental techniques to examine this model.

Wide Range Dielectric Spectroscopy

Dielectric spectroscopy is one of the most commonly used techniques for the investigation of the dynamic response of glass-forming materials. The tremendous slowdown of the particle motions when approaching the glass transition and especially the fast processes in glass-forming materials, which have come into the focus of scientific interest recently, make the investigation in a wide frequency ...
