Materials research for group IV semiconductors: growth, characterization and technological developments IV

Group IV semiconductors lie at the heart of many electronic and photovoltaic devices. Major challenges for fundamental research and technological development are no longer confined to bulk silicon, but also to other group IV materials and a wide variety of silicon-based structures, such as alloys, nanostructured and nanocomposite materials, composite systems, thin and thick films, and heteroepitaxy on patterned silicon substrates. Advances in device performance are underpinned by new defect engineering procedures, development of novel growth techniques, and improvements in advanced diagnostic tools. Point and extended defects remain at the center of interest, and in some cases their engineering represents an option for new functionalities (e.g. spintronic devices).
