Van der Waals Forces Used to Tune Properties of Ferroelectric Thin Films, NC State Researchers Show
Crispy enough to crunch, soft enough to enjoy. A good bake.
Summary
Researchers at North Carolina State University have demonstrated that van der Waals forces can be used to tune the physical and electronic properties of ferroelectric thin films. This discovery opens new possibilities for engineering materials used in smaller, more energy-efficient electronic devices. The work focuses on epitaxy—depositing crystalline layers on other crystalline layers—and how van der Waals interactions at the interfaces can influence material properties in ways previously not well understood.
Key quotes
· 2 pulledEpitaxy is when you deposit a crystalline layer of material on top of another crystalline layer of material.
When you are doing this with thin films, van der Waals forces can play an unexpected role in determining the properties of the resulting material.
