Carbon nanomaterials

Carbon is unique material providing diversity of forms and shapes in its condensed state. Naostructured carbons, such as fullerenes, carbon nanotubes, nanodiamonds, graphene, are especially attractive for researchers because of unusual properties and exciting perspectives for practical applications.

In our group we are developing methods for production and modification of carbon (and especially nanocarbon) materials with use of a plasma enhanced chemical vapour deposition (CVD) and laser assisted processes. The obtained materials are characterized with use laser Raman spectroscopy, electron microscopy and other methods. Our research interests in application of the nanocarbon materials are related mainly to electronics and photonics.
