摘要
In dielectric, piezoelectric, and pyroelectric effects, the contributions of ferroelectricity, heteropolar charge, and homopolar charge can be studied separately by using differential time domain spectroscopy method. For a same sample, by measuring the dielectric and pyroelectric spectra, the components of heteropolar and homopolar charges can be separated. In pyroelectric effect, the components of these charges have opposite signs.
