Researchers squeeze atomic arrangements

Abstract:
The key was in finding the perfect mismatch. Materials Science and Engineering Professor Chang-Beom Eom and his team grew a material of slightly larger atomic structure upon a slightly smaller substrate. Eom engineered strain into barium titanate (BaTiO3) thin films giving the material ferroelectric properties that could lead to cleaner, smaller, faster and more efficient memory and electro-optic devices.
