25 February 1993Surface acoustic wave propagation in an organic nonlinear optical crystal
The first demonstration of Surface Acoustic Wave (SAW) propagation in a polar organic crystal, (-)-2-(alpha) -methylbenzylamino-5-nitropyridine (MBANP) is reported. A SAW velocity of 1416 ms-1 in the [010] direction, in the (001) crystal plane was measured, which is about half that of many inorganic substrates. In addition 3 of the 8 piezoelectric coefficients, d21, d22, d23 have been measured and indicate that performance comparable with lithium niobate may be achieved.
