Crystal growth, experimental and theoretical studies on the electronic structure of CNGS and Nd:CNGS

Abstract: CNGS) single crystals were grown using the Czochralski technique, and the dielectric, elastic and piezoelectric properties of the Nd:CNGS crystals were evaluated at room temperature by the impedance method. It is proved that the Nd:CNGS crystals have larger dielectric constants, piezoelectric constants and elastic compliance as compared with the CNGS crystals. The electronic structure and chemical composition of the crystals were analyzed using X-ray photoelectron spectroscopy (XPS). Constituent element repres… Show more

“…The values of d 14 reported by Karaki et al (2004) and Shi et al (2006) differ by more than 15% from the results in this work. On the other hand, our results agree well with those reported by Ren et al (2016). A possible reason for this difference is that in the studies by Karaki et al (2004) and Shi et al (2006) the crystals were grown using a stoichiometric compound, while for the crystals used by Ren et al (2016), as well as in the present work, an excess of Ga 2 O 3 was added to the crystal growth raw material.…”

“…The previously studied sample of the CNGS crystal was used for measurements of independent piezoelectric moduli d 11 and d 14 [ 8 ]. It is found that the measured piezoelectric moduli are in good agreement with the results obtained on a crystal grown under the same growth conditions (an excessive Ga 2 O 3 was added to the crystal growth raw material) [ 9 ], and differ by more than 15% from crystals obtained under the conditions of a stoichiometric compound with a mixture of N 2 and 1–3 vol% O 2 as used in the growth atmosphere [ 10 , 11 ]. Obviously, the difference in growth conditions affects the microdefect structure of crystals.…”

“…The presence of such defects can affect the magnitude of piezoelectric constants of the material. It can explain the differences in the measured values of piezoelectric coefficients of CNGS single crystals obtained under different growing conditions [ 8 , 9 , 10 , 11 ].…”
