摘要:The monoclinic alpha-BiB306 (alpha-BIBO) crystal has been actively studied for nonlinear optical applications, but with limited efforts for piezoelectric usages. In this work, the temperature dependence of the electroelastic properties for alpha-BIBO crystal was investigated over the temperature range of -150-150 degrees C, where the alpha-BIBO crystal was found to possess low dielectric loss (<0.5%) and minimal variation of relative dielectric permittivities (< +/-10%). The temperature coefficients of elastic compliances were obtained to be on the order of 0.2-5.1 x 10(-4)/degrees C. Moreover, the alpha-BIBO crystal was determined to own good temperature stability of electromechanical properties, with coupling factors being 13-32.1% at room temperature, while the independent piezoelectric coefficients shifted differently as a function of temperature with the first order temperature coefficients evaluated to be on the order of -0.3-17.9 x 10(-4)/ degrees C. The above temperature characteristics of the electro-elastic properties are important for designing piezoelectric sensors operational over a broad temperature range. (C) 2016 Elsevier B.V.
