Custom Made 2D crystals

Custom Made 2D crystals

Over the past years we have produced many custom-made crystals on demand. Examples are semiconductors with p- or n- type doping, 2D alloys with a specific composition (MoWS2, MoWSe2, etc) or other new TMDC's

Our scientific staff has the expertise in the production and characterization of large size and high purity single crystals. The crystals are characterized with EDX, X-ray diffraction (single crystal XRD and powder XRD), Raman and additionally with Hall measurements.

The single crystal MoWSe2 is characterized using:

XRD: single crystal and powder X-ray diffraction (D8 Venture Bruker and D8 Advance Bruker)
EDX: Energy-dispersive X-ray spectroscopy for stoichiometric analysis
Raman: 785 nm Raman system
