Graphene monolayers engineered to adopt a corrugated conformation are found to exhibit very pronounced lateral expansion characteristics upon uniaxial stretching in specific directions, i.e. giant negative Poisson's ratio (auxeticity). Such anomalous properties are manifested in‐plane and may be controlled through the shape and amplitude of the wave‐like pattern of the corrugation, which in the case of graphene may be controlled through the introduction of patterned ‘defects’. This confirms… 

Magic auxeticity angle of graphene

Research on the auxetic behavior and mechanical properties of periodically rotating graphene nanostructures

Abstract Negative Poisson’s ratio (auxetic) material is one of the most widely studied metamaterials, and recent attempts have been made to discover auxeticity in graphene-based and related

Chemically modified graphene films with tunable negative Poisson’s ratios

It is reported that the microstructural hierarchy of pristine chemically modified graphene films, featuring wrinkles, delamination of close-packed laminates, their ordered and disordered stacks, renders remarkable negative Poisson’s ratios ranging from −0.25 to − 0.55.

Smart Honeycomb “Mechanical Metamaterials” with Tunable Poisson's Ratios

Mechanical metamaterials represent a class of deformable systems, which exhibit macroscopic deformations, mechanical, and/or thermal properties. These emerge due to the structure of their subunits

On the Design of Multimaterial Honeycombs and Structures with T‐Shaped Joints Having Tunable Thermal and Compressibility Properties

Honeycombs made from more than one material are proposed and analyzed with the help of finite element simulations. It is shown that such honeycombs are designed to change their shape when subjected

Boron arsenate and its pressure-dependent auxetic properties

The mechanical properties of single crystals boron arsenate, BAsO4, are simulated through density functional theory simulations over a wide range of pressures from −10 to +90 GPa. It was shown that



Elastic properties of chemically derived single graphene sheets.

The elastic modulus of freely suspended graphene monolayers, obtained via chemical reduction of graphene oxide, was determined through tip-induced deformation experiments, pointing toward a 2-fold role of the oxygen bridges, that is, to impart a bond reinforcement while at the same time impeding the charge transport.

Intrinsic Negative Poisson's Ratio for Single-Layer Graphene.

This work reports that single-layer graphene exhibits an intrinsic NPR, which is robust and independent of its size and temperature.

Elastic properties of hydrogenated graphene

There exist three conformers of hydrogenated graphene, referred to as chair-, boat-, or washboard-graphane. These systems have a perfect two-dimensional periodicity mapped onto the graphene scaffold

Hierarchical Auxetic Mechanical Metamaterials

Using simulations on typical hierarchical multi-level rotating squares, it is shown that, through design, one can control the extent of auxeticity, degree of aperture and size of the different pores in the system, making the system more versatile than similar non-hierarchical ones.

Electronic properties of graphene multilayers.

It is shown that the quasiparticle decay rate has a minimum as a function of energy, there is a universal minimum value for the in-plane conductivity of order e(2)/h per plane and, unexpectedly, the c-axis conductivity is enhanced by disorder at low doping, leading to an enormous conductivity anisotropy at low temperatures.

Properties of graphene: a theoretical perspective

The electronic properties of graphene, a two-dimensional crystal of carbon atoms, are exceptionally novel. For instance, the low-energy quasiparticles in graphene behave as massless chiral Dirac

Measurement of the Elastic Properties and Intrinsic Strength of Monolayer Graphene

Graphene is established as the strongest material ever measured, and atomically perfect nanoscale materials can be mechanically tested to deformations well beyond the linear regime.

Origami based Mechanical Metamaterials

We describe mechanical metamaterials created by folding flat sheets in the tradition of origami, the art of paper folding, and study them in terms of their basic geometric and stiffness properties,

Electronic properties of graphene

Graphene is the first example of truly two‐dimensional crystals – it's just one layer of carbon atoms. It turns out that graphene is a gapless semiconductor with unique electronic properties

Reentrant Origami-Based Metamaterials with Negative Poisson's Ratio and Bistability.

This study shows analytically and experimentally that the Poisson's ratio changes from positive to negative and vice versa during its folding motion, and verified the bistable mechanism of the reentrant 3D TMP under rigid origami configurations without relying on the buckling motions of planar origami surfaces.
