GRAPHENE / SHEETS

Using a plasma-supported CVD process graphene can be produced in the form of planar single crystals which have amazing qualities. 
The monocrystalline layers are extremely rigid and tensile-resistant. The modulus of elasticity of graphene (approximately 1020 giga-pascals) corresponds to that of normal graphite along the basal planes. This is almost the strength of diamond. 

The electrical properties of the graphene layers are also remarkable. Because of the lack of a bandgap the material behaves like an electrical conductor with high mobility of electrons and holes. This suggests the use in electronic applications. Graphene also has excellent optical properties. Light is reduced by only about 2.3 percent when passing through the material and evenly over the entire visible spectrum. In the field of photovoltaics graphene could thus replace indium tin oxide (ITO) as a contact material.

Currently hot topics are also: massless contact material for micro (nano)-electro-mechnical structurs (filter-systems in 5G communication), water purification, super capacitors and terahertz electronics.

Diacara will advise you on these and other promising ideas.le to those of a single-crystalline graphene layer, this does not imply a limitation for some applications (e.g. energy storage technology).
