Study of Amorphous to Microcrystalline Structure Change of Hydrogenated Si -- What Stabilizes the Aole of H in these films has been widely recognized to terminate the Si dangling bonds through forming Si-H bonds reducing greatly gap states. With this reduction of the gap states, the addition of reasonable concentration of dopants such as P or B can move the Fermi level to give either n-or p-type

NMR Study of Structure and Bonding in Glasses,ng in SiO. and B.O. has been investigated using the oxygen-17 isotope. The O. NMR spectrum for vitreous SiO. (v-SiO.) exhibits well-defined structure and indicates significant local order in the material. Matching of experimental and computer-simulated spectra permits extraction of the O. quadrupole

Magic-Angle Sample-Spinning Nuclear Magnetic Resonance Spectroscopy of Silicate Glasses: A Review,ral environment of atoms in both crystalline and amorphous solids. In this paper we will briefly review the theory of MASS NMR and some of the data for crystalline silicates and silicate glasses. We will demonstrate that MASS NMR using various nuclides (primarily silicon-29, aluminum-27, and oxygen-
