일반 설명

A single-layer graphene film on a copper substrate.
This product is provided with a PMMA coating on top of the graphene in order to ease the transfer process and to avoid contamination. It′s a high quality product with great homogeneity.

Graphene film
  • Growth method: CVD synthesis
  • Appearance: Transparent film
  • Transparency: > 97%
  • Coverage: > 95%
  • Number of graphene layers: 1
  • Thickness (theoretical): 0.345 nm
  • FET Electron Mobility on Al2O3: 2000 cm2/Vs
  • FET Electron Mobility on SiO2/Si: 4000 cm2/Vs
  • Sheet Resistance on SiO2/Si: 450±40 Ω/sq (1cm x1cm)
  • Grain size: Up to 10 μm

Substrate Cu Foil
  • Thickness: 18 μm
  • Pre-treated for easier bottom layer removal: monolayer graphene on the back side of copper is partially removed, but not completely. Therefore, an additional treatment like RIE is needed before transfer to eliminate the bottom layer totally.

PMMA Coating
  • Spin coated for high homogeneity
  • Molecular weight: 495k
  • Thickness: <100 nm
  • PMMA model: 495K, A2

애플리케이션

  • Graphene research
  • Flexible batteries
  • Electronics
  • Aerospace industry
  • MEMS and NEMS
  • Micro actuators
  • Conductive coatings

Graphene has been attracting great interest because of its distinctive band structure and physical properties. Today, graphene is limited to small sizes because it is produced mostly by exfoliating graphite. We grew large-area graphene films of the order of centimeters

질문

  1. Hi, can I know which side of the copper foil has a monolayer graphene? Is it facing up or down? I just wanted to make sure before I use it.

    1 답변

    1. Graphene should be on top of the Cu foil. Since graphene has PMMA protection, a simple way is to start the Cu etching and see which side the Cu foil is on.
