Structure-related infrared optical properties of Ba(ZrxTi1−x)O3 thin films grown on Pt/Ti/SiO2/Si substrates by low-temperature processing

Optical characterization of SnO2:F films by spectroscopic ellipsometry

“…This technique is a non-destructive, powerful and accurate technique [40,41] and is based on the polarized light [42]. SE is able to measure the thickness and dielectric function of a multi-layer system simultaneously [43][44][45]. So, it is a powerful technique to explore the band structure of nanometric semiconductor through the determination of the complex dielectric function [42].…”

Surface chemical states of barium zirconate titanate thin films prepared by chemical solution deposition

“…Many efforts have been made to improve the dielectric properties of the BZT thin film capacitors, including using conductive oxide electrodes such as (La 0.7 Sr 0.3 )MnO 3 [12], LaNiO 3 [13,14], and (La 0.7 Ca 0.3 )MnO 3 [15]. Effect of seed layers on dielectric properties of Ba(Zr 0.3 Ti 0.7 )O 3 thin films [16], and infrared optical properties of BZT thin films have been reported [17][18][19].…”

Infrared optical properties of ferroelectric 0.5BaZr0.2Ti0.8O3–0.5Ba0.7Ca0.3TiO3 thin films

“…The absorption curve can be used to calculate the absorbance of the related infrared devices. The absorption coefficient of the BCZT50 thin films is larger than that of PbTiO 3 -based [9,10] and BZT [12] thin films on similar substrates. Given that it has a large pyroelectric coefficient, BCZT50 thin films may be a significant and promising material for infrared detectors and arrays.…”

“…However, the application restricts from toxicity of lead based materials stimulate the research for environmentally friendly alternatives with excellent pyroelectric properties. Some ferroelectric thin films, such as barium titanate, bismuth sodium titanate and potassium sodium niobate films etc., have been intensively investigated these years [11][12][13][14][15]. However, their performances are far from being satisfactory enough to replace PZT.…”
