The Nobel Prize winning scientists Professor Andre Geim and Professor Kostya Novoselov have taken a huge step forward in studying the wonder material graphene and ...
Physicists have definitively observed an intensely studied anomaly in condensed matter physics -- the even-denominator fractional quantum Hall state -- via transport measurement in bilayer graphene.
A recent study published in Nano Letters sheds new light on the intricate behavior of electron transport in bilayer graphene, ...
Magic angle graphene superlattice. (Courtesy: P Jarillo-Herrero) Researchers have found that electrons organize themselves into a new kind of ferromagnet in twisted bilayer graphene (TBG). In this ...
Researchers have identified a new class of quantum states in a custom-engineered graphene structure. The study reports the discovery of topological electronic crystals in twisted bilayer ...
Electron transport in bilayer graphene exhibits a pronounced dependence on edge states and a nonlocal transport mechanism, ...
Graphene normally has a band gap of zero, which is related to its massless electrons. In 2007, a team of physicists showed that the electrons in bilayer graphene — a sheet of carbon two atoms thick — ...
UT Dallas theorists, along with colleagues in Germany, have for the first time observed a rare phenomenon called the quantum anomalous Hall effect in bilayer graphene. Results were published Oct ...
“In twisted bilayer graphene, at certain ‘magic’ twist angles these bands evolve into flat bands because the interlayer coupling between the layers is adjusted to the right spot,” says Chiu. In these ...
