CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishDilute nitrides, in particular In$_x$Ga$_{1-x}$As$_{1-y}$N$_y$ are very interesting alloys because of their actual and potential applications in the field of telecommunications and photovoltaic. A full knowledge of the local structure around each kind of atom, in particular the local ordering, is of fundamental importance because it is predicted to affect the electronics properties of these alloys. In this work we investigated the local environment of N and In by X-Ray Absorption Fine Structure, paying particular attention to demonstrate that N is substitutional to As and preferentially links In atoms
