Tearing of free-standing graphene [PDF]
Physical Review E, 2013 We examine the fracture mechanics of tearing graphene. We present a molecular dynamics simulation of the propagation of cracks in clamped, free-standing graphene as a function of the out-of-plane force.

Deuterium Adsorption on Free-Standing Graphene [PDF]
Nanomaterials, 2021 A suitable way to modify the electronic properties of graphene—while maintaining the exceptional properties associated with its two-dimensional (2D) nature—is its functionalisation.

Corrugations in Free-Standing Graphene
Nanomaterials, 2022 Although both the tendency of 2D materials to bend out of plane as well as its effect on materials’ properties are well known, the factors influencing this phenomenon have not been extensively studied.

Free-standing bilayer metasurfaces in the visible [PDF]
Nature CommunicationsMulti-layered meta-optics have enabled complex wavefront shaping beyond their single layer counterpart owing to the additional design variables afforded by each plane.

Flexural phonons in free-standing graphene [PDF]
Physical Review Letters, 2007 Rotation and reflection symmetries impose that out-of-plane (flexural) phonons of free-standing graphene membranes have a quadratic dispersion at long wavelength and can be excited by charge carriers in pairs only.

Free‐Standing Halogen‐Bonded Nanosheets Formed by Ultrasonic Liquid Exfoliation [PDF]
Advanced ScienceStrong in‐layer interactions are typically considered a key requirement for exfoliating layered materials to form nanosheets. Here, the formation of free‐standing nanosheets held together by halogen bonding interactions is reported for the first time ...

Mechanical and Electrical Properties of Free‐standing Polycrystal Diamond Membranes [PDF]
Advanced ScienceIn this study, we demonstrate a novel approach for synthesizing free‐standing and transferable polycrystalline diamond membranes (PCDm) to overcome these constraints, thus enabling a much wider spectrum of applications. Two types of PCDm cantilevers —Top‐

Free-Standing Epitaxial Graphene [PDF]
Nano Letters, 2009 We report on a method to produce free-standing graphene sheets from epitaxial graphene on silicon carbide (SiC) substrate. Doubly clamped nanomechanical resonators with lengths up to 20 microm were patterned using this technique and their resonant motion was actuated and detected optically.
