Structure and electronic properties of low-dimensional systems and molecular assemblies

Objective

Low-dimensional structures and molecular assemblies in the nanometre range exhibit an enormous potential for applications in future electronic data storage and processing devices. Such structures are particularly interesting when created through the process of self-assembly on suitable substrates. Vicinal surfaces are ideally suited as patterned templates for the mass fabrication of one-dimensional structures on the nanometre scale, where conventional lithographic techniques are no longer feasible or afford able. Vicinal surfaces display a two-fold symmetric morphology and, consequently, a complete anisotropy of all physical properties that is retained upon atom or molecule adsorption and thin-film growth. Furthermore, one-dimensional patterns of steps, facets and atomic rows with periodicities on a scale of 1nm to 100nm can be produced.

We will investigate the structure and electronic properties of
(i) low-dimensional structures (quantum wires, dots, and stripes) and
(ii) molecular assemblies of periodic structures prepared on vicinal semiconductor and metal substrates.

Our interests are specially centred on the formation and final structure of atomic or molecular chains and their corresponding electronic structure. In the latter case we will focus on the reconstruction of the electron wave functions and the temporal evolution of quasi-particles (holes and electrons), characterised by a finite lifetime that can be analysed by scanning tunnelling and photoemission spectroscopy.
