| Abstract: | The electrical property of a KTiOPO4 single crystal was studied by means of a dielectric spectroscopy method in the temperature range from −100 to 100 °C. Dielectric dispersion began at a temperature, TS=−80 °C. It is believed that this dielectric dispersion is related to the ionic hopping conduction, which arises mainly from the jumping of K+ ions. The activation energy concerned with hopping conduction is Ea∼0.20 eV above TS. TS=−80 °C can be the minimum temperature for the hopping K+ ion. |
