Temperature and frequency dependences of the electric properties of CLBO crystals
In this paper, CsLiB6O10 (CLBO) crystals were grown by top-seeded solution growth (TSSG) method using self-flux. The temperature and frequency dependences of the dielectric constant, dielectric loss, AC conductivity and impedance spectroscopy for different cuts CsLiB6O10 crystals were investigated, also temperature characteristics of the resonance frequency and electromechanical coupling were studied. The results show that (0 0 1)-plane of CsLiB6O10 crystal has the highest dielectric constant with a value of 109, highest AC conductivity and highest electromechanical coupling factor of about 17% at elevated temperature, these make CsLiB6O10 crystal excellent candidate for electrical application at elevated temperature. Also the anisotropy of electric properties has strong relationship with the crystal structure.
