Researchers have developed a way to make twisted oxide materials over much larger areas while maintaining precise control over how their layers are rotated. "Our work here demonstrates it is possible to use layers of oxide materials that are connected by strong chemical bonds - while precisely controlling the twist angle between crystalline oxide membranes. "The strong interlayer bonding we found between oxide layers suggests there may be entirely new interfacial phenomena to explore," adds Xu. Strong Bonds Reshape the Atomic LatticeThe scientists used synchrotron X-ray diffraction to examine the boundary where the two oxide layers meet. "Our work demonstrates a technique for creating large-area oxide twistronic materials with controlled twist angles and a strong chemical bond between layers," says Xu.
