Energy efficient nonvolatile data storage utilizing tiny capacitors made from new family of ferroelectric materials

"The new materials are made with magnesium-substituted zinc oxide thin films. The film was grown via sputter deposition... deposited at much lower temperatures than other ferroelectric materials... next step... making them into capacitators that are approximately 10 nanometers thick and 20 to 30 nanometers in lateral dimensions, which is a difficult engineering challenge... [potentially] cell phones with chips that use much less energy, allowing sustained operation for a week or more"
