Characterization of LSM-YSZ composite electrode by ac impedance spectroscopy
Jae-Dong Kim,Goo-Dae Kim,Ji-Woong Moon,Yong-il Park,Weon-Hae Lee,Koichi Kobayashi,Masayuki Nagai,Chang Eun Kim +7 more
TL;DR: In this article, the characteristics of La1−xSrxMnO3 perovskite (LSM)-yttria-stabilized zirconia (YSZ) composite electrodes were studied over a range of compositions by ac impedance spectroscopy.
Journal ArticleDOI
Effect of carrier concentration on optical bandgap shift in ZnO:Ga thin films
TL;DR: In this paper, a modified BM effect equation was proposed to substitute the nonparabolic BM effect and bandgap narrowing (BGN), and the exponent in the modified BM equation was affected by carrier concentration.
Journal ArticleDOI
Analysis of Bias Stress Instability in Amorphous InGaZnO Thin-Film Transistors
TL;DR: In this article, an analysis of electrical bias stress instability in amorphous InGaZnO (a-IGZO) thin-film transistors (TFTs) is presented.
Journal ArticleDOI
Influence of Al2O3 diffusion barrier and PbTiO3 seed layer on microstructural and ferroelectric characteristics of PZT thin films by sol-gel spin coating method
TL;DR: In this paper, a spin-casted Pb(Zr0.52Ti0.48)O3 [PZT] thin film with Al2O3 buffer layer and PbTiO3 seed layer was successfully prepared at a low temperature of 550°C.
Journal ArticleDOI
