Abstract
A ferroelectric material includes a mixed crystal having AlN and at least one nitride of a transition metal. The proportion of the nitride of the transition metal is selected such that a direction of an initial or spontaneous polarity of the ferroelectric material is switchable by applying a switchover voltage. The switchover voltage is below a breakdown voltage of the ferroelectric material.
