Controlled synthesis of few-layer SnSe2 by chemical vapor deposition

Synthesis of few-layer hexagonal boron nitride thin film by chemical vapor deposition.

In this contribution we demonstrate a method of synthesizing a hexagonal boron nitride (h-BN) thin film by ambient pressure chemical vapor deposition on polycrystalline Ni films. Depending on the growth conditions, the thickness of the obtained h-BN film is between ∼5 and 50 nm. The h-BN grows continuously on the entire Ni surface and the region with uniform thickness can be up to 20 μm in late...

Growth and properties of few-layer graphene prepared by chemical vapor deposition

The structure and the electrical, mechanical and optical properties of few-layer graphene (FLG) synthesized by chemical vapor deposition (CVD) on a Ni-coated substrate were studied. Atomic resolution transmission electron microscope (TEM) images show highly crystalline single-layer parts of the sample changing to multi-layer domains where crystal boundaries are connected by chemical bonds. This...

Single- and few-layer graphene growth on stainless steel substrates by direct thermal chemical vapor deposition.

Increasing interest in graphene research in basic sciences and applications emphasizes the need for an economical means of synthesizing it. We report a method for the synthesis of graphene on commercially available stainless steel foils using direct thermal chemical vapor deposition. Our method of synthesis and the use of relatively cheap precursors such as ethanol (CH(3)CH(2)OH) as a source of...

Controlled Growth of Graphene by Chemical Vapor Deposition

Graphene, firstly isolated in 2004, is a new type of carbon materials, which contains a singleor few-layered sheet of Sp2-bonded carbon atoms. This special atomic structure gives graphene rich physical properties and wide potential applications. It has excellent electrical, mechanical, thermal and optical properties and has wide applications in nano-electronic devices, transparent conductive fi...
