Electric Charge Transport and Dielectric Properties of the Barium Titanate Ceramics Obtained by Spark-Plasma Sintering with Different Carbon Content

Oleksandr S. Pylypchuk, Victor V. Vainberg, Denis O. Stetsenko +9

Barium titanate (BaTiO3) ceramics with a different content of carbon were synthesized by spark-plasma sintering (SPS) at the temperature of 1100 C in vacuum under pressure. The con…

Colossal dielectric response of HfxZr1-xO2 nanoparticles

Oleksandr S. Pylypchuk, Victor V. Vainberg, Vladimir N. Poroshin +10

We reveal a colossal dielectric response of small (5 - 10 nm) oxygen-deficient HfxZr1-xO2 nanoparticles (x = 1 - 0.4), prepared by the solid-state organonitrate synthesis. The effe…

The impact of morphological structure and flexo-chemical strains on the electric transport mechanisms in the molybdenum-disulfide-oxide nanoflakes

Oleksandr S. Pylypchuk, Victor V. Vainberg, Vladimir N. Poroshin +11

Electric conduction mechanisms are studied in the pressed nanoflake powder of the molybdenum-disulfide-oxide (MoSxOy) depending on their content and structure. The MoSxOy nanoflake…
