Researchers at City University of Hong Kong have made a groundbreaking discovery in the field of materials science, uncovering a new vortex electric field with potential to enhance electronic, magnetic, and optical devices.
According to Professor Ly Thuc Hue, generating this field was previously challenging due to expensive techniques and complex procedures. However, her team has developed an innovative method using bilayer 2D materials that can easily induce the vortex electric field.
The team’s technique involves a simple twist in bilayer 2D materials, which allows for the creation of a broad spectrum of twist angles ranging from 0 to 60 degrees. This breakthrough enables the manipulation and creation of twisted bilayers freely.
The discovery also leads to the formation of a 2D quasicrystal, potentially enhancing future devices. The vortex electric field generated depends on the angle of the twist, offering versatile applications in various fields.
Future research will focus on manipulating the material further, such as testing layer stacking possibilities or exploring effects from other materials. With their patented ice-assisted transfer technique now accessible, the team hopes to collaborate globally to generate more discoveries.
