Abstract :
Theoretical results of acoustic-surface-wave (a.s.w.) zero-frequency-temperature-coefficient (f.t.c.) configurations in Tl3TaSe4 are discussed. Six selected cuts with an electromechanical coupling coefficient of up to 4% are described, as well as a zero-f.t.c. and zero-power-flow-angle cut with 2% coupling.
