The peculiarity of electric conductance of KDP single crystals
The electrical conductivity of KDP crystals grown by the solvent recirculation and temperature lowering methods has been investigated in the 20-150°C temperature range. The temperature dependences follow an exponential law. The pre-exponential factor and activation energy have been determined. A cor...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The electrical conductivity of KDP crystals grown by the solvent recirculation and temperature lowering methods has been investigated in the 20-150°C temperature range. The temperature dependences follow an exponential law. The pre-exponential factor and activation energy have been determined. A correlation between pre-exponential factor and the conductance activation energy has been found to exist in undoped crystals within the temperature interval of 20-100°C and the activation energy range of 0.49-0.79 eV. The correlation coefficient is 0.98. This testifies that electrical conduction mechanisms are similar in crystals with low concentration of defects. The results obtained are discussed within the frame of known electrical conduction mechanisms in KDP based on the proton transport. |
