Using this pioneering instrument, researchers have observed—for the first time—the interactions between electrons and an exotic atomic vibration in twisted sheets of graphene, called a phason.

Graphene is widely popular among two-dimensional (2D) materials due to its exceptional physical and electronic properties. Its bilayer form is synthesized by stacking two graphene monolayers; twisting ...

A study published in the journal Nature led by Princeton researchers reveals in precise detail how and why a material known as magic-angle twisted bilayer graphene forms insulating quantum phases.

In 2018, Jarillo-Herrero discovered that when two graphene sheets are stacked on top of each other, at a precise, "magic" angle, the twisted structure -- known as magic-angle twisted bilayer ...

The magic angle refers to a specific angle of rotation between two stacked layers of two-dimensional (2D) materials, such as graphene, transition metal dichalcogenides (TMDs), and hexagonal boron ...

Physics with a twist: New findings on graphene Date: November 7, 2024 Source: Florida State University Summary: Researchers now reveal how various physical manipulations of graphene, such as ...

Researchers at IMDEA Nanociencia have developed an analytical method to explain the formation of a quasi-perfect 1D moiré pattern in twisted bilayer graphene. The pattern, naturally occurring in ...

Graphene is a simple material containing only a single layer of carbon atoms, but when two sheets of it are stacked together and offset at a slight angle, this twisted bilayer material produces ...

Applying this novel technique to twisted bilayer graphene yielded a surprising discovery: a unique low-energy vibration known as a “phason,” whose coupling to electrons grows stronger as the ...
