Optical Properties of Low Dimensional Silicon Structures

Stefano Ossicini is Full Professor of General Physics at the Faculty of Engineering (Reggio Emilia) of the University of Modena and Reggio Emilia (Italy) and Director of the PhD School in 'Physical and NanoSciences' of the University of Modena and Reggio Emilia. He also work a researcher within the CNR-National Institute for the Physics of Matter (INFM) at the INFM National Center S3 nanoStructures and bioSystems at Surfaces". He graduated in Physics in 1976 at the University of Rome. From 1978-82 he was active as post-doc and assistant at the Department of Theoretical Physics of the Free University in Berlin (Germany). From 1982-984 researcher at the University of Calabria (Italy). 1984 he went to the University of Modena and Reggio Emilia (Italy). His research activity has mainly focused on the theory of low-dimensional- and nano- systems. In recent years the central topic of his research has been, in particular, the investigation of the structural, electronic and optical properties of semiconductor nanostructures.

The workshop on "Optical Properties of Low Dimensional Silicon sL Structures" was held in Meylan, France on March, I yd, 1993. The workshop took place inside the facilities of France Telecom- CNET. Around 45 leading scientists working on this rapidly moving field were in attendance. Principal support was provided by the Advanced Research Workshop Program of the North Atlantic Treaty Organisation (NATO). French Delegation a l'Armement and CNET gave also a small financial grant, the organisational part being undertaken by the SEE and CNET. There is currently intense research activity worldwide devoted to the optical properties of low dimensional silicon structures. This follow the recent discovery of efficient visible photoluminescence (PL) from highly porous silicon. This workshop was intended to bring together all the leading European scientists and laboratories in order to reveal the state of the art and to open new research fields on this subject. A large number of invited talks took place (12) together with regular contribution (20). The speakers were asked to leave nearly 1/3 of the time to the discussion with the audience, and that promoted both formal and informal discussions between the participants.
