Pack of 5 plates of graphene on silicon carbide substrate plate with dimensions of 1 cm by 1 cm by 330 µm

Graphene is present in the circle with a diameter of 1 cm on square 1 cm by 1 cm SiC plates. The tolerance of a plate’s dimensions is ±10%. Properties of graphene are given after choosing a specific number of layers.

Properties of graphene regardless of the number of layers:

  • Phase: monocrystal on the whole sample
  • Method of production: partly reversible graphitisation of SiC (0001) under silicon atoms’ flux
  • Electrical properties: doped, type n, electric charge neutral point (Dirac point) around 0.35 eV below Fermi level

Properties of a substrate:

  • Material: silicon carbide (SiC)
  • Phase: monocrystal
  • Thickness: 330 µm (±25 µm)
  • Surface orientation: <0001> (±0.5 °)
  • The concentration of micropipe-type defects (MPD): 15 cm-2
  • Resistivity: 1E5 Ω cm
  • Band gap: 3.23 eV
  • TTV / Bow / Warp: 15 µm / 25 µm / 25 µm
  • Thermal conductivity along a axis in 298 K: 4.9 W/cm K
  • Thermal conductivity along c axis in 298 K: 3.9 W/cm K

Characterisation:

Results of characterisation techniques such as ARPES, XPS, spectrophotometry, Raman spectrometry, and AFM are available upon request.
