Growth service

  • Growing high crystalline monolayer and multilayer TMDs (MoS2, WS2, MoSe2, WSe2, …) (10 to 200 µm crystals with large coverage)
  • We can grow on the following substrates directly:
    • Si
    • SiO2
    • Sapphire
    • SiC
    • GaN
    • Diamond
  • We can transfer TMDs on any desirable substrate
  • Growing TMD crystals on 3D nanostructures
  • Growth on nonhomogenous surfaces

Device fabrication

We can provide high-quality 2D-based electronic and optoelectronic devices with your design! Our standard device fabrication is on SiO2/Si. You can send your own substrate or give us a hint about your desired substrate.

  • Fabrication of photodetector, transistors
    and phototransistors based on TMDs

Please provide us with the necessary information about the device design such as:

  1. Material (MoS2, WS2, MoSe2 ….)
  2. Length and width of the channel
  3. The type and thickness of the oxide (top gate- bottom gate)(Al2O3, …)
  4. Gate thickness
  5. The thickness of the contacts (e.g. Ti (10 nm)/Au (50 nm))
  6. Area of the contact pads (100 to 100 µm)
  7. Layout design (optional)
  8. Special treatment on the device (please provide us the detail)
  9. 3d or 2d graphic of the device (favorable)
  10. Number of the wafers (4 inches) or chips (1 cm to 1 cm)(or your desired size)
