A method to measure the electric charge injected/extractedat the metal-dielectric interface
A method was proposed to determine the sign and the value of the electric charge injected/extracted at the metal-dielectric interface. The method is based on the modification of the external electric field of a dielectric when electric charge is injected/extracted onto its surface. The lowest surfac...

| Summary: | A method was proposed to determine the sign and the value of the electric charge injected/extracted at the metal-dielectric interface. The method is based on the modification of the external electric field of a dielectric when electric charge is injected/extracted onto its surface. The lowest surface charge density measured in the presented experiments was around

. The method is insensitive to the orientational polarization. The charge carriers injection/extraction process takes place no matter if there is a conduction current through the sample. |
