ONYX THz-TDS Graphene & 2D Materials Characterisation

Brand: Das-Nano

Product Code: ONYX-THz

Availability: On Request

Onyx is the first THz-TDS system in the market designed to provide a full-area non-destructive characterization of Graphene, thin-films, and other 2D materials. Onyx covers the gap between the macro and the nano scale tools characterizing from 0,5 mm2 to large areas (m2), enhancing the industrialization of the research materials.

Compared to other large-area methods, such as the four-probe methods, Onyx is capable to measure the spatial distribution of the quality of the sample. Spatial resolution in the order of few hundreds of microns enable the fast characterization of large areas of sample as opposed to microscopic methods such as Raman, SEM, and TEM.


Onyx is continuously improving its features offering new results highly increasing its potential. Now, Onyx incorporates Mobility and Carrier Density analysis to its previous capabilities.

In just one single measurement, the system is able to provide precisely the following physical properties:

  • DC conductance, σDC
  • DC resistance, RDC
  • Carrier scattering time, 𝜏sc
  • Carrier density, Ns
  • Carrier mobility, μdrift


  • Uniformity & Homogeneity inspection
  • Electrical Conductance and Resistance
  • Electrical Mobility and Carrier Density
  • Quality control of full sample
  • T-Wave emitter/receptor co-developed with Fraunhofer Institute
  • Sample size: from 1x1mm to 200x200mm (8”).
