The piezoelectric behaviour of Tl3BX4-crystals (B = V,Nb,Ta; X = S,Se) has been investigated. They show a very strong piezoelectric effect. The values of the piezoelectric modulus d123 at 163 K range from 76.7 × 10−12 m/V (Tl3VS4) to 55.6 × 10−12 m/V (Tl3TaSe4). Apart from substances with ferroelectric phases, the Tl3BX4-compounds exhibit the strongest piezoelectric effect known.
Zeitschrift für Kristallographie – Crystalline Materials offers a place for researchers to present results of their crystallographic studies. The journal includes theoretical as well as experimental research. It publishes Original Papers, Letters and Review Articles in manifold areas of crystallography.
