Invited

Inorganic nanoparticles have been investigated as components in various functional materials and devices for diverse applications. These nanomaterials can be prepared as pure phases or as multi-phase materials which in turn are used as fillers in polymer matrices in order to fabricate nanocomposites. In this communication chemical aspects that have been particularly relevant in our research...

17. Perturbed Angular Correlations studies of Hg coordination mechanisms on functionalized magnetic nanoparticles

Vitor Bras de Sequeira Amaral (Universidade de Aveiro, Department of Physics, CICECO, Portugal)

Accepted

Water pollution by trace heavy metals (such as mercury, cadmium) is a serious environmental and public problem. The development of efficient new materials and clean-up technologies for removing those metals from water to within the legal admissible concentrations is urgent. In the last few years, a new type of eco-nanomagnets composed of amorphous SiO2 shells coating magnetite (Fe3O4)...

19. Laplace Deep Level Spectroscopy ... a new tool for semiconductor research at ISOLDE

Prof. Anthony Peaker (Photon Science Institute, University of Ma)

08/12/2010, 14:50

Accepted

A comprehensive understanding of impurities and lattice defects has been central to the development of semiconductor devices. The electronic properties of these impurities depend on the chemical species, the site of the impurity in the lattice and its possible complexing with other impurities and lattice defects such as vacancies. A very important tool in the study of defects and impurities is...

25. Direct identification of interstitial Mn in Ga1−xMnxAs and evidence of its high thermal stability

Lino Pereira (IKS KU leuven)

Accepted

The lattice location of Mn in GaAs has been intensively studied in recent years due to its crucial role on the magnetic properties of Ga1−xMnxAs, one of the most studied dilute magnetic semiconductors. Maximum Curie temperatures (TC) are usually achieved after low temperature annealing (~200ºC), which is generally attributed to out-diffusion of interstitial Mn (MnI). However, despite major...
