A study of the crystal chemistry, electron density distributions, and hydrogen incorporation in the Al₂SiO₅ polymorphs
The Al₂SiO₅ polymorphs have been examined to provide new insights into their chemical bonding, their crystal chemistry, their equations of state, and the incorporation of water in the form of hydroxyl in their structures. The Al₂SiO₅ polymorphs provide a unique structural assemblage for a crystal …

Generation-Annealing of Interface Traps and Hydrogenation of Boron Acceptors in Metal-Oxide-Silicon Capacitors Irradiated by Kilo-Volt Electrons
Generation and annealing of interface traps and deactivation of boron acceptors in silicon are investigated in Al/SiO$\sb2$/Si capacitors exposed to 8 keV electrons. Post-oxidation conditions are varied. Interface and oxide traps are separated using a repeated stress-anneal technique with the …

Ab initio calculations of mechanical, thermodynamic and electronic structure properties of mullite, Iota-alumina and boron carbide
… of ceramics. Except for the end member (x=0), Al₂SiO₅ the crystal structures of the other phases, called mullite, have partially occupied sites. Stoichiometric supercell models for the four mullite phases 3Al₂O₃ • 2SiO₂, 2Al₂O₃ • SiO₂ , 4Al₂O₃ • SiO₂ , 9Al₂O₃ • SiO₂ , and ι-Al₂O₃ (iota-alumina) …

Relationship between the chemical composition, lattice parameters, and optical properties of andalusite and its isostructural analogs
… ranging from relatively pure andalusite (Al₂SiO₅) to about 62 mole percent kanonaite (MnAlSi0₅). Of the 20 crystals, 8 contained significant Fe³⁺ in addition to Mn³⁺ and, in the literature, were called viridines. Linear regressions were performed on the data using, successively, na, nb, …

Resistive Switching Behavior in Low-K Dielectric Compatible with CMOS Back End Process
In an effort to lower interconnect time delays and power dissipation in highly integrated logic and memory nanoelectronic products, numerous changes in the materials and processes utilized to fabricate the interconnect have been made in the past decade. Chief among these changes has been the …
