Abstract
High-frequency coherent phonons may be generated by piezo-materials. Bonding of thin crystal platelets or epitaxial deposition by evaporating or sputtering are convenient methods. The disadvantages of these methods are the bond problem for high frequency and low temperature, orientation, complicated technology and the time consumption. A new,simple, fast method with a small thermal load of the substrate is the use of the piezoelectric polymer Poly (vinylidene fluoride) [Fig.1]. The bulk material cpnstants in longitudinal mode of PVDF ((k=0.12, c=2200 m/s, Z=2.5·106 kg/s m2) have similar values as CdS (k=0.17, c=4500 m/s, Z=21.5·106 kg/s m2) 1,2].
