  • Abstract
    Theoretical results are presented for the piezoelectric coupling of a surface-acoustic-wave thin-film transducer on a silicon substrate having a nonzero electrical conductivity. It is shown that, for specific combinations of the material layer thicknesses, this conductivity disappears. Also, under certain conditions, the enhancement in the piezoelectric coupling is degraded.
