    Synthesis and in-situ Mo microalloying of CuCr alloy by aluminothermic self-propagating reduction by Jin-ru Han, Zhi-he Dou, Ting-an Zhang, Wang An

    Published 2025-03-01
    “…Therefore, the conductivity of CuCrMo alloy is increased from 12.63 MS m−1 to 17.41 MS m−1. Based on the performance of 12 kV vacuum interrupter assembled with self-propagating CuCr contacts, it is found that compared with CuCr alloy, the insulation, chopping current and breaking performance of the interrupter are obviously improved by adding Mo.…”

    Fabrication of Electrospun Porous TiO<sub>2</sub> Dielectric Film in a Ti–TiO<sub>2</sub>–Si Heterostructure for Metal–Insulator–Semiconductor Capacitors by Jin-Uk Yoo, Tae-Min Choi, Sung-Gyu Pyo

    Published 2024-09-01
    “…Improved electrical properties were observed with increasing TiO<sub>2</sub> anatase content, and the residual amount of PVDF decreased with increasing annealing temperature. The sample annealed at 600 °C showed a lower leakage current than those annealed at 300 and 450 °C, with a leakage current density of 7.5 × 10<sup>−13</sup> A/cm<sup>2</sup> when Vg = 0 V. …”
