Polymorphic 2D materials allow structural and electronic phase engineering, which can be
used to realize energy-efficient, cost-effective, and scalable device applications. The phase …

Graphene, a single layer of carbon atoms in a honeycomb lattice, offers a number of
fundamentally superior qualities that make it a promising material for a wide range of …

Abstract Two-dimensional (2D) materials are crystalline materials made of a single or a few
layers of atoms. They have been an active research subject in recent years because of their …

Graphene, in its ideal form, is a two-dimensional (2D) material consisting of a single layer of
carbon atoms arranged in a hexagonal lattice. The richness in morphological, physical …

Graphene has demonstrated great potential in next-generation electronics due to its unique
two-dimensional structure and properties including a zero-gap band structure, high electron …

Graphene on nickel is a prototypical example of an interface between graphene and a
strongly interacting metal, as well as a special case of a lattice matched system. The …

Graphene has become the focus of research recently due to its properties. Various methods
have been proposed for the synthesis of graphene, and chemical vapour deposition (CVD) …

Moiré superlattices have recently become excellent platforms for studying new properties of
two-dimensional (2D) layered materials. With periodic moiré patterns, moiré superlattices …

Although macroscale superlubricity reduces the friction of graphene materials, industrial
application has been limited to special environments or complex strain engineering. Herein …

We use low-energy electron microscopy to investigate how graphene grows on Cu (111).
Graphene islands first nucleate at substrate defects such as step bunches and impurities. A …
