Abstract

2D materials such as graphene, MoS2 and phosphorene are promising candidates for resonating mechanical sensors due to excellent tunable electrical/- mechanical properties, low masses, and maximal surface to volume ratios. Mechanical resonators based on supsended graphene have been realized. - CVD graphene wet-transferred onto 10x10 mm Si/SiO2 chips with Au electrodes - Graphene patterned in O2 plasma with a resist mask - Graphene is released by etching SiO2 in BHF and critical point drying

Graphene

Graphene (ˈgræfiːn) is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice nanostructure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds. Each atom in a graphene sheet is connected to its three nearest neighbors by σ-bonds and a delocalised π-bond, which contributes to a valence band that extends over the whole sheet.

Single-layer materials

In materials science, the term single-layer materials or 2D materials refers to crystalline solids consisting of a single layer of atoms. These materials are promising for some applications but remain the focus of research. Single-layer materials derived from single elements generally carry the -ene suffix in their names, e.g. graphene. Single-layer materials that are compounds of two or more elements have -ane or -ide suffixes. 2D materials can generally be categorized as either 2D allotropes of various elements or as compounds (consisting of two or more covalently bonding elements).

Potential applications of graphene

Potential graphene applications include lightweight, thin, and flexible electric/photonics circuits, solar cells, and various medical, chemical and industrial processes enhanced or enabled by the use of new graphene materials. In 2008, graphene produced by exfoliation was one of the most expensive materials on Earth, with a sample the area of a cross section of a human hair costing more than

1,000 as of April 2008 (about

100,000,000/cm2). Since then, exfoliation procedures have been scaled up, and now companies sell graphene in large quantities.
