Abstract

The elastic and piezoelectric properties of single crystals of paratellurite (TeO2) are investigated. In the <110 > direction, shear waves may propagate with the extremely low phase velocity of 0.6 × 103ms−1. The coupling coefficient for shear waves in the <001 > direction is of the order of 10%. Direct excitation of torsional vibrations is possible using a very simple electrode configuration. There are certain directions in which the phase velocity of shear waves is independent of temperature.

    Tellurium oxide (TeO2) is a P-type semiconductor with wide band gap and interesting nonlinear optical properties [1–3]. At ambient conditions, TeO2 has three polymorphs: α-TeO2 (paratellurite, space group: P41212) [4–6], β-TeO2 (tellurium, space group: Pbca) [7] and γ-TeO2 (space group: P212121) [8,9]. All the three polymorphs can be described as different arrangements of corner-sharing TeO4 unit (the distorted trigonal bipyramids).

    For example, the most popular AO material – tellurium dioxide is known for its extremely high acoustic anisotropy [15,16]. The crystalline media characteristics which are important for AO interaction realization (namely the acoustic wave velocity and the refraction indices) depend on temperature [17–20]. Hence, the characteristics of AO devices depend on temperature also [7,10,12,21].
