Graphene Synthesis by Carbon Nanotubes Exfoliation
Experimental work will focuse on carbon nanotubes exfoliation by oxidation or alkaline metals intercalation. Carbon nanotubes and synthesised graphene ribbons will be characterized by Raman spectroscopy, FTIR, STM, AFM and other advanced methods.
2D Nanomaterials Synthesis - „bottom-up“ Processes
2D inorganic materials based on MoS2 and similar substances show quite unique properties. Materials will be synthesised from various precursors under hydrothermal conditions. Process optimalization leads to preparation of materials with desired structure and number of layers. Characterization will be done by advanced analytical techiques like AFM, Raman spectroscopy and photoluminescence measurements.
