Calibration of the pulsed electroacoustic method for measuring space charge density

Abstract

A technique for calibrating the charge quantity using the pulsed electroacoustic (PEA) method is described in this paper. The space charge calibration technique is shown to depend on the electric and acoustic properties of the samples when the standard signal for calibration is obtained from the sample itself. Moreover, an advanced calibration technique using the reference signal measured from a different material is described in detail The experimental results obtained using the advanced calibration technique show that the error of every measurement is less than 10 %.
