Ferroelectric material stable at near-atomic thickness reveals new route to low-power electronics

Scientists discovered a ferroelectric material that retains spontaneous polarization at a thickness of a few atomic layers. This opens a path to denser and more energy-efficient memory and miniature electronic components.

• Material retains ferroelectric properties at near-atomic thickness
• Polarization can be switched by external electric field
• Discovery could accelerate creation of energy-efficient memory
