- Аннотация: Single-crystal Pb5Ge3O11 films 5–105 μm thick, adhering well to platinum substrates, were prepared by pyrolysis of metalorganic precursors in combination with in situ sol-gel processing. The best films consisted of densely packed crystallites ranging in size from 200 to 300 μm, with hexagonal habits. A welldefined ferroelectric transition was revealed at 170–180°C. The typical parameters of the films are ɛ20 = 30–40, tan δ ≃0.02, ɛmax ≃200, Ps = 3.2 μC/cm2,E c = 16 kV/cm, and ρ = 108-109 Ω cm, in agreement (except for ɛmax) with those of lead germanate crystals
