Since the discovery of graphene, novel layered materials with diverse properties are discovered or predicted in a daily basis. In addition, combining these materials in stacked structures offers limitless possibilities of novel structures to meet target functionalities. These infinite possibilities can be yet infinitely multiplied by turning the knob that controls the twist angle between neighboring layers. Upon relative rotation between layers, twisted systems develop a so-called “Moiré pattern” that effective creates a superlattice of the combined layered system. This opens a new subfield of graphene and 2D materials research called “twistronics”. Of particular impact was the discovery of superconductivity in twisted bilayer graphene near the so-called “magical angle”, where bands near the Fermi level become flat, that gave rise to investigations of a variety of strongly-correlated phenomena in these materials, which remain one of the hottest topics in condensed matter physics until today.
The goal of this Research Topic is to explore the frontiers of research in twisted bilayer graphene and related systems (such as twisted multilayer graphene). We welcome Original Research, Review, Mini Review and Perspective articles on themes including, but are not limited to:
• All aspects of these so-called Moiré systems.
• Experimental and theoretical investigations addressing the origins of superconductivity in twisted graphene systems, which appears to be of unconventional type, as well as other strongly correlated effects
• Challenging aspects of twisted graphene systems, such as state-of-the-art developments in assembly, characterization and applications of these Moiré systems are also important topics in this collection.
For this Research Topic on the “Recent Advances on Twisted Bilayer Graphene”, we welcome contributions on the following topics:
• Synthesis and controlled assembly of Moiré systems
• Direct structural characterization of the Moiré systems (Moiré angle and lattice relaxation), based on scanning tunneling microscopy (STM), transmission electron microscopy (TEM), electron diffraction, tip-enhanced Raman spectroscopy (TERS), and other techniques
• Optical and vibrational spectroscopies, such as photoluminescence and Raman scattering
• Electron transport measurements under magnetic field and related devices
• Theory and simulation of twisted graphene systems
Keywords:
Graphene, twisted, Moiré, superconductivity, 2D materials, bilayer
Important Note:
All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
