Effect of partial nitridation on the dielectric constant of A5Ta4O15 (A=Sr, Ba)

Novel double anisotropic conductive flexible composite film endued with improved luminescence

“…Polyaniline (PANI) has become one of the most studied conductive polymers for its following unique advantages: (a) simple synthesis; 14 (b) chemical stability 15 and excellent electrochemical performance; 16 (c) unique doping phenomenon; 17 (d) high conductivity; 18 (e) good environmental stability. 19 As the above merits mentioned, PANI has been used in electromagnetic shielding technology, 20 anti-static technology, 21 solar cells, 22–24 catalytic materials and secondary battery materials.…”

Size-dependent disproportionation (in ~ 2–20 nm regime) and hybrid Bond Valence derived interatomic potentials for BaTaO2N

“…Barium tantalum oxynitride (BaTaO 2 N) has been widely studied because of its high dielectric constant, especially in the radio frequency region (k = 4900 at 1 MHz) (Kim et al 2004) and light-harvesting capabilities (due to its desirable direct band gap of ~ 2.1 eV). This allows its use in prospective applications that involve electrostatic energy storage (Han et al 2017) and visible light harvesting (Fang et al 2003;Wang et al 2016). However, post-synthesis heat treatments such as sintering and annealing significantly affect the physico-chemical properties of this material.…”

“…However, post-synthesis heat treatments such as sintering and annealing significantly affect the physico-chemical properties of this material. For example, heat treatment results in a decrease in dielectric constant k in this kind of materials (Wang et al 2016;Han et al 2017). Given how essential heat treatments are to device fabrication and material deployments, relevant molecular dynamic studies can be important.…”
