CVD Growth high purity copper foil

Copper foil for Graphene growth

Graphene Platform are commercial providers of Graphene and 2D Materials, specialising in business to research, providing consistent high-quality growth throughout the world.

Research Graphene and 2D material are synthesised using a Linear Process Chemical Vapour Deposition (PLCVD) or Chemical Vapour Deposition (CVD)  techniques in which a Hydrocarbon process gas is ‘cracked’ by either heat or an Induced Plasma with lower heat, during this process, the released carbon atoms/ions ( not now connected to Hydrogen) are in the correct ‘state’ to form a layer of carbon onto the surfaces of the CVD reactor. By using the right copper foil, increases the likelihood of nucleation, that is to say, carbon is more likely to locate onto the copper foil where it can attach (Van de Walls forces) onto a similar compound such as carbon.

The formation a Graphene, being a single layer of carbon atoms forming a ‘lattice’ like structure, grows as the substrate provides the right environment, during the CVD process, to allow free movement of the copper atoms to arrange themselves forming a stable lattice we know as Graphene.

One of the key factors for Graphene growth is using the right copper foil.

Graphene Platform’s copper foil has been developed to provide high rates of synthesis of graphene.

Specially treated for monolayer graphene growth, the copper foil is 0.035mm thick and a purity greater that 98.5%. The localised surface carbonation increases nucleation during CVD process facilitating growth

Our high purity copper foil is the preferred choice, used by leading commercial Graphene growth companies and research laboratories worldwide.

Planartech, CVD growth system manufacturers are one of the preferred users of this copper foil

 

The A4 (297mm x 210mm) sheets are sold in packets of 10.

Scroll/Dry Vacuum Pump

Scroll/Dry Vacuum Pumps

Iwatta Scroll Vacuum Pump

Brief outline of low vacuum pumps.
Low pressure vacuum pumps also known as backing pumps can be divided in to three sections

  • Rotary Vane – Oil seals
  • Dry Diaphragm pump
  • Dry Scroll pump

The Diaphragm pump is a dry, oil free pump which is commonly used where only a small vessel is evacuated, these are used in small laboratory apperatus.
The Rotary vane pump is more commonly used for larger vessels, the design is simple. But for the very increasing demand for “clean vacuum”, the oil used for the sealing makes this pump not ideal, as the oil tends to escape from the pump molecular form and works it’s way against the ‘flow’ entering the vacuum vessel causing contamination.

When pumping gasses that can contaminate the oil causing further problems, such as the oil viscosity change which can lead to pump failure.

Dry Scroll vacuum pumps have been designed to generate laminar atomic flow but hermetically sealing the pump from the driving mechanism.
Vacuum is achieved by using one fixed and one rotary orbiting inter-levered Archimedean spiral shaped chamber walls called ‘scrolls’. The gas enters the scroll arrangement and is forced, almost by peristaltic movement, to move towards the centre of the arrangements, with each movement the compress liquids or gases are further compressed until they reach the centre where they are released as exhaust gas.

The motor and gearing is sealed from the pumping scroll arrangement ensuring that these pumps remain oil free.
The applications in brief are:

  • Vacuum Extraction – NON-Chemical or corrosive applications
  • Vacuum Heat Treatment contamination free pumping
  • Vacuum Pick Up for industrial processes
  • Vacuum Oven or Freeze Drying
  • Air conditioning – evacuation of Freon lines
  • Gel drying or composite manufacturing

Kodial Zero Length Viewports With Broadband Anti-Reflective Coatings

VacTechniche Kodial viewports are offered with a four-layer broadband anti-reflective (BBAR) coating on both sides of the window optimised to a customer specified wavelength range. In many cases, the coating reduces reflection to below 0.5% per face or 1% total at the key wavelengths specified. Please advise the important wavelengths or wavelength range with your enquiry or order.

Wavelength ranges between 240 nm and 1550 nm can be accepted as standard, although coatings for other wavelength ranges can be quoted on request. Viewports with ‘V’ coatings for a single wavelength for laser applications are also offered. VacTechniche Kodial viewports are offered in CF, ISO and KF flange styles.
