Latest Patents

Kyung-Jin Choi holds a patent for "Strain-engineered ferroelectric thin films." This patent describes a strained thin film structure that includes a substrate layer made of crystalline scandate material. The structure features a strained layer of crystalline ferroelectric that is epitaxially grown with respect to the substrate layer, maintaining a strained state. The design ensures that the thickness of the ferroelectric layer remains below the point at which dislocations begin to occur. An intermediate layer may also be included, which carries the lattice structure of the underlying substrate layer. The properties of the ferroelectric film are significantly enhanced compared to bulk ferroelectric materials, making them suitable for applications such as ferroelectric memories.
