D. thesis. SiC is fabricated starting from single-crystalline silicon (Si) substrates by carbonization or by ion implantation. The characterization of these structures allows to gather data and better physical and chemical understanding of these systems.The main objectives are (i) the fabrication and characterization of SiC and other interesting crystalline phases obtained from Si wafers and (ii) to demonstrate that these products are a viable way for using them as templates, compliant, seed or buffer layers in SiC or III-N overgrowth by epitaxial growth techniques. These approaches let the consecution of a crystalline quality enough to the development of devices. Indeed, their use allow a significant reduction of the high defect density present in III-N or SiC alloys compared to their quality when directly grown on Si.
