Sol-gel deposited Pb(Ti,Zr)O3 thin films have been used to integrate pyroelectric arrays on silicon. The arrays of 1×12 (element size of 600 × 1100 mm2) and 1×50 elements (element size of 140 × 1100 mm2) are fabricated by standard photolithograph

Polycrystalline La-modified lead titanate thin films have been processed, by a diol-based sol-gel route, on Si-based substrates. Multiple deposition and crystallization steps were carried out in order to promote heterogeneous nucleation and, as a con
