Main Results:

  • Demonstrated two types of vertically conducting devices: Au|graphene|Au and Co|graphene|Co.
  • Au|graphene|Au junctions showed high magnetoresistance (up to 400%) at room temperature.
  • Co|graphene|Co junctions exhibited a robust spin valve effect at room temperature.

Conclusions:

  • A versatile method for creating functional graphene vertical structures was established.
  • The demonstrated devices hold promise for applications in magnetic field sensors and spintronic devices.
  • Layer-by-layer assembly provides a novel pathway for advanced graphene vertical architectures.
