A suspended graphene-based optical interferometric …

By using a suspended graphene membrane, the sensitivity is expected to increase compared to that of conventional surface stress sensors, which have a typical thickness of 100–1000 nm, even though the Young's modulus of graphene is up to 1 TPa. 37 In addition, the suspended graphene is a highly sensitive chemical and a biosensor with a small ...

Optomechanics for thermal characterization of …

The thermal response of graphene is expected to be extremely fast due to its low heat capacity and high thermal conductivity. In this work, the thermal response of suspended single-layer graphene membranes is investigated by characterization of their mechanical motion in response to a high-frequency modulated laser. A characteristic delay time $\ensuremath{\tau}$ between the optical intensity ...

Free-Standing Single-Atom-Thick Iron Membranes …

Carbon or other covalently bonded materials, like boron nitride, can form two-dimensional sheets because of the strong bonding between the atoms. In contrast, metals share electrons in a three-dimensional delocalized way, and this could preclude the formation of thin stable sheets. Nevertheless, Zhao et al. (p. [1228][1]) observed pure iron membranes suspended across the pores in a graphene …

Fluorination of suspended graphene | SpringerLink

2017-4-29 · Suspended graphene is exposed to different fluorine-containing species produced by a plasma source fed with CF4 precursor gas. We investigate the fluorination process by selecting two different kinetic energies for the ions striking the graphene surface. The chemical-bonding environment is discussed, and the control of the graphene-fluorination homogeneity is investigated at the individual ...

Broken-Symmetry States in Doubly Gated Suspended …

Bilayer graphene samples are expected exhibit quantum Hall states that are ferromagnetic with different types of spin ordering. Weitz et al. (p. [812][1], published online 14 October) studied the conductance of high-quality suspended bilayer graphene samples. They used an applied perpendicular electric field to induce transitions between the different broken-symmetry states that appear at low ...

Suspended Wavy Graphene Microribbons for Highly ...

Their excellent stretchable and electrochemical performance relies on the suspended wavy structures of graphene microribbons. This avoids the detachment and cracks of the electrode materials. In addition, it ensures the electrode fingers keep a relatively constant distance so the stability of the microsupercapacitors can be enhanced.
