Nano-Carbon & 2D Materials

2D materials such as carbon nano-tubes, graphene or transition metal dichalcogenides (TMDs) show immense promise in many applications such as transistors, sensors, and optoelectronics. Flexible and adaptive analytical methods can support effective investigation and accelerate progress in 2D materials research and development.

For comprehensive investigations of nano-carbon and TMD samples, Oxford Instrument witec360 Raman microscopes can be equipped with additional imaging techniques such as Atomic Force Microscopy (AFM), Scanning Near-field Optical Microscopy (SNOM) and Scanning Electron Microscopy (SEM). All provided imaging techniques can be fully integrated in a single device.
