摘要：

We show that when a typically antiferroelectric material such as PbZrO3 or BiNbO4 is deposited as a thin film on a semiconducting substrate (Si), it displays ferroelectric behavior below a critical film thickness characteristic of the system. In an attempt to understand this "size effect," we consider the contributions of residual strain and the self-biasing effect produced by the intrinsic electric field at the semiconductor-insulator interface.
