Antiferroelectric materials with double hysteresis loops are attractive for energy storage applications, which becoming increasingly important power electronics nowadays. Among them, AgNbO3 based lead-free ceramics have attracted intensive interest as one of promising environmental-friendly candidates. However, most the suffers from low dielectric breakdown strength (Eb). The limitation Eb is broken to some extent in this work. Here, epitaxial films were fabricated by pulsed laser...
Transparent conductive film (TCF) is a material that integrates electrical conductivity and optical transparency. It widely used as an electrode in thin-film solar cells. However, considerable progress needed to facilitate its high performance low-cost preparation. In this study, preparation scheme for AlF3 GaF3 co-doped ZnO (FAGZO) thin films was designed implemented by magnetron sputtering (MS). The mutual restraint between the properties wide-spectrum transmission of resolved....
We develop a ferroelectric nanohybrid that improves photocatalytic efficiency by reducing the recombination of holes and electron charge carriers.
Transparent conductive films (TCFs) are crucial components of solar cells. In this study, F, Cl, and Ga co-doped ZnO (FCGZO) TCFs were deposited onto a glass substrate using the sol-gel spin-coating method rapid thermal annealing. The effects F-doping content on structural, morphological, electrical, optical properties FCGZO examined by XRD, TEM, FE-SEM, PL spectroscopy, XPS, Hall testing, UV–vis–NIR spectroscopy. All prepared exhibited hexagonal wurtzite structure preferentially grew along...

AbstractResistive random access memory is promising for next-generation nonvolatile memory, which has high density, low power consumption, and fast read/write speed. However, the resistive switching (RS) mechanism in oxide ferroelectric thin film devices still unclear. In this paper, Pt/BiFeO3/La0.5Sr0.5CoO3(Pt/BFO/LSCO) heterostructures were deposited on (111)SrTiO3(STO) substrates by magnetron sputtering. X-ray diffraction confirmed epitaxial relationship between...
Gas targets hold distinctive significance and advantages in the field of laser-matter interaction. As a major type gas targets, supersonic target is one most commonly used for laser wakefield acceleration (LWFA).
