Twisted Bilayer News Today

By identifying the controllable nonlinear Hall effect in twisted bilayer graphene, a group of international researchers led by The University of Hong Kong (HKU) and The University of Science and Technology (HKUST) achieved a significant advancement in the field of quantum materials.

In an article published in ACS Applied Materials & Interfaces, researchers demonstrated the creation of higher-order artificial oxide heterostructure based on various materials and symmetries.

An article published in Communications Physics discussed partially filled states of flat-band structures induced by thermodynamically stable corrugation of the graphene bilayer via an interlayer twist.

Parallels are predicted between the behavior of electrons in twisted bilayer graphene and in a class of materials known as heavy fermion materials.

Quantum Hall (QH) effect allows the exploitation of quantum coherence of electrons for various applications from metrology to quantum computation. QH interferometry is a convenient tool that provides an archetypal platform to achieve fractional QH state braiding statistics. However, a phase coherence along the length of the interferometer and suppression of Coulomb charging energy is required to observe fractional statistics.

In the last five years, the discovery and significant interest in twisted bilayer graphene gave rise to an entirely new subfield in advanced materials science and quantum physics: twistronics. In a new study, scientists apply machine learning algorithms to discover more about this remarkable phenome

Researchers use elevated resolution tip-enhanced photoluminescence (TEPL) microimaging to analyze excited electron funneling in a twisted bilayer MoS2.
