Researchers from the City University of Hong Kong have made a groundbreaking discovery in vortex electric fields, which could have a significant impact on future electronic, magnetic, and optical devices. A new vortex electric field with potential to enhance these devices has been observed by the team.
According to Professor Ly Thuc Hue, the team used an innovative ice-assisted transfer technique to create twisted bilayer materials, allowing them to manipulate and create the vortex electric field freely. This breakthrough is highly valuable as it can upgrade the operation of many devices, including strengthening memory stability and computing speed.
The discovery also has implications for quantum computing, spintronics, and nanotechnology. The team’s technique enabled them to create a broad spectrum of twist angles ranging from 0 to 60 degrees, which could lead to various applications such as ultrafast mobility and speed for computing, dissipationless polarization switching, novel polarizable optical effects, and advancements in spintronics.
The researchers have patented their ice-assisted transfer technique, which they believe can be used globally to achieve clean bilayer interfaces without extensive and expensive procedures. This could lead to a new field focused on twisting vortex fields in nanotechnology and quantum technology.
According to Professor Ly, the discovery has the potential to be a major game-changer in device applications such as memory, quantum computing, spintronics, and sensing devices. The team is looking forward to continuing their research and exploring its full potential.
