High Performance Near-Room-Temperature Pyroelectric Energy Harvesting Characteristics of Ferroelectric–Semiconductor Composites

“…Note that the Ba 1 –y (Bi 0.5 Li 0.5 ) y TiO 3 with y = 0.15 (BBLT) composition exhibits the T C at 45 °C and hence has been chosen as the ferroelectric phase of the composite for this study . The semiconducting ZnO is selected as another constituent phase of the composite due to its large thermal conductivity compared to those of other ceramics . The fabricated BBLT: x ZnO composites with x = 0.0, 0.1, and 0.2 are subjected to pyroelectric energy harvesting and pyroelectric sensor characteristics.…”

Study of Electrical and Dielectric Behaviors of Copper-Doped Zinc Oxide Ceramic Prepared by Spark Plasma Sintering for Electronic Device Applications

“…To address this challenge, our research focuses on the synthesis and characterization of copper-doped ZnO nanoparticles and ceramics using controlled sol–gel methods and Spark Plasma Sintering (SPS) at a consistent temperature of 1000 °C. This investigation aims to unravel the intricate interplay between synthesis parameters and resulting electronic performance, contributing valuable insights to the ongoing advancements in the design and application of ZnO-based electronic materials [ 11 , 12 ]. Despite various studies exploring SPS sintering of ZnO, the need for innovative approaches that achieve both high relative densities and controlled grain sizes remains [ 13 , 14 ].…”

Design and fabrication of an ultra-high definition and ultra-thin color conversion layer for micro-LED displays

“…This approach concurrently realizes a more robust pixel structure and minimizes color crosstalk. To further optimize the effect of reducing the aspect ratio of the pixels, we introduce a nanomaterial, zinc oxide (ZnO), which exhibits a thermal conductivity four times higher than SiO2 and TiO2 nanoparticles (NPs) [6] . By incorporating ZnO nanoparticles with varied sizes, we can dramatically increase the efficiency of color conversion, enhance the emitted light brightness, reduce blue light leakage, and improve the heat resistance of the color conversion microarrays, ultimately achieving exceptionally high display quality.…”
