Sulfur and few-layer graphene interaction under thermal treatments

Mechanism of thermal conductivity reduction in few-layer graphene

Dimensional crossover of thermal transport in few-layer graphene.

Graphene, in addition to its unique electronic and optical properties, reveals unusually high thermal conductivity. The fact that the thermal conductivity of large enough graphene sheets should be higher than that of basal planes of bulk graphite was predicted theoretically by Klemens. However, the exact mechanisms behind the drastic alteration of a material's intrinsic ability to conduct heat ...

Thermal properties of graphene and few-layer graphene: applications in electronics

The authors review thermal properties of graphene and few-layer graphene (FLG), and discuss applications of these materials in thermal management of advanced electronics. The intrinsic thermal conductivity of graphene – among the highest of known materials – is dominated by phonons near the room temperature. The examples of thermal management applications include the FLG heat spreaders integrat...

Fe-catalyzed Etching of Graphene and Few-layer Graphene

Fe-catalyzed etching of graphite and few-layer graphene (FLG) has been used to create channels with desired crystalline edges [1,2]. Due to the strong Fe-C interaction, graphene can be etched through either carbon hydrogenation or carbon dissolution into Fe alone. In this work, we investigated the Fecatalyzed etching of graphene and few-layer graphene (FLG) in forming gas (10% H2/90% N2) or N2....

Electroburning of few-layer graphene flakes, epitaxial graphene, and turbostratic graphene discs in air and under vacuum

Graphene-based electrodes are very promising for molecular electronics and spintronics. Here we report a systematic characterization of the electroburning (EB) process, leading to the formation of nanometer-spaced gaps, on different types of few-layer graphene (namely mechanically exfoliated graphene on SiO2, graphene epitaxially grown on the C-face of SiC and turbostratic graphene discs deposi...
