HIGH RESOLUTION NMR OF 29Si IN AMORPHOUS HYDROGENATED SILICON

The new techniques of High Resolution NMR in solids by cross-polarization with protons and magic angles rotation of the sample have been applied to the study of amorphous hydrogenated Silicon in order to contribute to the characterization of this material. This method gives the possibility to distinguish (by their "chemical shifts") the different kinds of environments of each 29Si nucleus, in relation with the bonds in which these atoms are involved
