**Hong Kong –** City University of Hong Kong (CityUHK) researchers, in collaboration with local partners, have announced a groundbreaking discovery: a new type of vortex electric field generated within twisted bilayer 2D materials. This discovery has the potential to dramatically improve the performance of a wide range of electronic, magnetic, and optical devices.

The research, published [Insert Publication Details Here], reveals that a simple twist in the layering of 2D materials can induce this vortex electric field, a finding that significantly simplifies the previously complex and expensive production methods. The team achieved this breakthrough using a novel “ice-assisted transfer technique,” enabling the creation of pristine interfaces between bilayer materials with unprecedented control over twist angles (0-60 degrees), a significant improvement over previous limitations of less than 3 degrees.

This innovative technique not only simplifies the production process but also allows for the creation of 2D quasicrystals, structures known for their low thermal and electrical conductivity. These quasicrystals, formed as a result of the vortex electric field, are expected to enhance device durability, speed, and functionality. Potential applications include improved memory stability, faster computing speeds, more efficient polarization switching, and advancements in spintronics.

Professor Ly Thuc Hue of CityUHK’s Department of Chemistry, a key member of the research team, highlighted the versatility of this discovery, noting that the properties of the vortex electric field vary depending on the twist angle. The team utilized advanced four-dimensional transmission electron microscopy (4D-TEM) to analyze the materials and confirm their findings.

The researchers have already secured a patent for their ice-assisted transfer method, a technique they believe could significantly accelerate future research in related fields. Future work will focus on exploring the effects of stacking multiple layers and investigating the potential for similar phenomena in other materials. The team anticipates that this discovery could lead to significant advancements in various technologies, including quantum computing and nanotechnology.
