Electrical boundary conditions

The new physics emerging from two-dimensional films in the limit of a few unit cells has a host of exciting applications. However, understanding the ferroelectric properties of such engineered thin film systems requires taking into account not only the material but also its interfaces with electrodes, substrates or atmosphere; in other words, the electrical boundary conditions. In the case of a thin film these can even determine the ferroelectric polarization stability. The depolarizing field can place a lower limit on the film thickness capable of supporting a stable polarization.
