Terahertz research platform for bulk, thin films and 2D materials 


Terahertz research platform for bulk, thin films and 2D materials 


Terahertz research platform for bulk, thin films and 2D materials

Onyx is the first 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.

das-Nano develops terahertz technology at international level and already has 19 patents for its degree of innovation, 12 of which are terahertz.

Onyx system complies with the IEC TS 62607-6-10:2021 technical specification, published by the International Electrotechnical Commision (IEC). The IEC TS 62607-6-10:2021 deals with the sheet resistance measurement of graphene-based materials using terahertz time-domain spectroscopy.


New characterization models available

Onyx is continuously improving its features offering new results highly increasing its potential. Now, Onyx version 4.0 incorporates two new characterization models to its previous capabilities: Semiconductor thin film model and Two thick substrates model. These new features expand Onyx’s versatility and make it an ideal platform for researching an even wider variety of materials

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

  • Electrical conductivity
  • Electrical resistivity
  • Charge carrier mobility
  • Charge carrier density
  • Refractive index


And now also:

  • Dielectric parameters, ε’ and ε’’
  • Absorbed power
  • Single-frequency features
  • Thickness
