 Obiettivo del progetto (Objective)

'We will develop and use imaging techniques for direct probing of electron dynamics in low dimensional structures with orders of magnitude improvements in time and spatial resolution. We will perform our measurements not only on static structures, but on complex structures under operating conditions. Finally as our equipment can also probe structural properties from microns to single atom defects we can directly correlate our observations of electron dynamics with knowledge of geometrical structure. We hope to directly answer central questions in nanophysics on how complex geometric structure on several length-scales induces new and surprising electron dynamics and thus properties in nanoscale objects. The low dimensional semiconductors and metal (nano) structures studied will be chosen to have unique novel properties that will have potential applications in IT, life-science and renewable energy. To radically increase our diagnostics capabilities we will combine PhotoEmission Electron Microscopy and attosecond XUV/IR laser technology to directly image surface electron dynamics with attosecond time resolution and nanometer lateral resolution. Exploring a completely new realm in terms of timescale with nm resolution we will start with rather simple structure such as Au nanoparticles and arrays nanoholes in ultrathin metal films, and gradually increase complexity. As the first group in the world we have shown that atomic resolved structural and electrical measurements by Scanning Tunneling Microscopy is possible on complex 1D semiconductors heterostructures. Importantly, our new method allows for direct studies of nanowires in devices. We can now measure atomic scale surface chemistry and surface electronic/geometric structure directly on operational/operating nanoscale devices. This is important both from a technology point of view, and is an excellent playground for understanding the fundamental interplay between electronic and structural properties.'
