1. Research Activity

a) growth, structure and property of quasi one- and two-dimensional transition-metal di-, tri-, and tetra-chalcogenides (e.g. NbSe₃ and TaTe₄), characterised by a variety of temperature and composition dependent commensurate and incommensurate superstructures, charge-density wave modulation phases and short-range ordering,

b) investigation of nucleation and the initial stages of growth of ultra-thin metallic layers (Ag, Au), prepared by vapour deposition onto different metallic and semiconducting substrates of the layered transition-metal di- and tri-chalcogenides with different topographies (MoTe₂, WTe₂, NbTe₂, NbSe₃),

and
c) surface modification of the same materials on an atomic scale as a function of the tunneling parameters.
