Abstract

The pulsed electroacoustic (PEA) method and the piezo-electrically induced pressure wave propagation (PIPWP) method are compared. While the PEA method has been widely used as a measurement technique to observe space charge distributions in solid dielectric materials, the PIPWP method has not been widely used because of its relatively lower spatial resolution as compared to that of the PEA method. Therefore, in this research, an attempt has been made to improve the resolution of the PIPWP method. In this paper, principles of the generation and the detection of pressure waves in both PEA and PIPWP methods are summarized. Furthermore, the two methods are compared through observations of the generation, drift and trapping of carriers in an organic photoconductor (OPC).
