Achieving a new generation of microelectronic devices requires combining silicon with materials, such as ferroelectrics that allow the development of, for example, high density, nonvolatile memories. Ramesh and Schlom describe work ( Lee et al.) showing that a class of ferroelectrics that has been particularly challenging to grow, can be grown as a thin film on a silicon substrate with the optimal crystallographic orientation for nonvolatile ferroelectric memories.
