The general expressions for the effective piezoelectric constants for substrate-clamped films as function of film orientation were discussed. The piezoelectric constants of films with a tetragonal crystallographic structure were calculated for typical orientations. The piezoelectric constants were measured experimentally for single domain ferroelectric Pb(Zr 0.2Ti 0.8)O 3 thin films. The theoretical results were found to be in good agreement with the experimental observations.
