Ultrathin multiferroic films overcome 'dead layer' for energy-efficient AI chips

Researchers have created ultrathin multiferroic films that overcome the 'dead layer' effect, which suppresses electrical and magnetic properties at interfaces. The advance could enable AI microchips that operate at far lower voltages than today's devices.

• Multiferroics combine electrical and magnetic properties controlled by tiny voltages
• The 'dead layer' limiting ultrathin films has been overcome
• The material could enable energy-efficient AI chips
