Nb2O5-doped BaTiO3 semiconductor

open access: yes, 1996
Semiconducting Nb2O5-doped BaTiO3 was prepared and characterized by X-ray diffraction, electron microscopy, thermogravimetry, and electrical measurements. The addition of the Nb2O5 donor dopant does not affect the sequence of chemical reactions during the synthesis of the ceramic material.

Spin singlet small bipolarons in Nb-doped BaTiO3

open access: yes, 2006
The magnetic susceptibility and electrical resistivity of n-type BaTi{1-x}Nb{x}O3 have been measured over a wide temperature range. It is found that, for 0 < x < 0.2, dopant electrons form immobile spin singlet small bipolarons with binding energy around

Multifunctional TiO2‐Graphene Hybrid Interfaces for Printable High‐Energy‐Density Polymer Thin Film Capacitor

open access: yesAdvanced Electronic Materials, EarlyView.
ABSTRACT The rapid advancement of flexible and wearable electronics demands printable thin‐film capacitors that combine high dielectric performance with scalable fabrication. However, achieving this balance in polymer dielectrics remains challenging, as enhancements in dielectric constant typically come at the expense of increased loss and reduced ...

Enhanced Lattice Polarization and Directed Charge Transport Toward Pt Surface Sites Accelerate the Volmer Step in Piezocatalytic H2 Evolution on Co‐Doped BiFeO3

open access: yesAdvanced Energy Materials, EarlyView.
We report a Pt‐decorated Co‐doped BiFeO3 (Pt/BCFO) piezocatalyst achieving an H2 evolution rate of 1896.4 µmol g−1 h−1. Co‐doping induces lattice distortion, enhancing piezoelectric polarization, while Pt sites promote water dissociation. Embedded in a poly(vinylidene fluoride) matrix, Pt/BCFO enables efficient mechanical energy harvesting and catalyst
