Voltage-dependent ionic polarization in TlBr: alternate square-wave bias application for ionic polarization control

Abstract

Scientific insights into the polarization of TlBr pellets under applied voltage were investigated to develop stable TlBr-based electronic devices. The polarization originates from the electrophoretic migration of Tl⁺ and Br⁻ ions and shows a clear dependence on the applied voltage. Importantly, the polarization can be effectively suppressed by applying an alternate square-wave bias.
