LABORATORIO DI MATERIALI E NANOSTRUTTURE

Students at the end of the course should have:
A good and flexible knowledge about scientific research and technology regarding the actual synthesis and the characterization of naostructured materials; a relevant know how about modern materials science and nanotechnology, both theoretical and experimental, and good capability about scientific methodology.

Basics of physics and experimental methodologies for the following techniques: Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), ion implantation, Rutherford Backscattering Spectrometry (RBS), thin film deposition by sputtering, photoluminescence. Fundamentals of vacuum technology.

There are two main experiments that consist of sample preparation and characterization:
1) Synthesis of porous germanium by ion implantation, properties and characterization.
The experimental consists of: ion implantation, SEM and RBS characterizations.
2) Synthesis and characterization of silicon nanodots.
The experimental consists of sputtering deposition of SiOx, thermal treatment, characterization by RBS and photoluminescence.
