The chapter discusses that the structure of the oxygen-related centers in other semiconductors have a great similarity to the forms in silicon, but that the relative strength of the bonds between O and the atoms of the crystal can allow for instance the formation of OH bonds not found in ...
Nevertheless, the complementary Frenkel defect to theF-type center—a single interstitial oxygen—still remains the most hidden primary defect in α-Al2O3and other wide-gap metal oxides. The main efforts to find experimental manifestations of radiation-induced oxygen interstitials have been undertaken ...

We also identify an oxygen exchange mechanism occurring through the annihilation of two peroxyl O atoms when they approach each other, where oxygen is released from the network as an O2 molecule leaving a perfect SiO2 structure. The energetics of other possible scenarios for atomic desorptions in ...
Atomic Structure refers to the fundamental components of matter, namely atoms, which consist of a nucleus and orbiting electrons. The nucleus, acting as the center of an atom, is positively charged and has a much greater mass than the negatively charged electrons. Atoms are electrically neutral ...
The small relaxation of the surface, referred to as rumpling, is exhibited and shown to have barely no effect on the adsorption of Ag on the surface. The oxygen site is found to be the most stable for Ag atom adsorption, in good agreement with previous ab initio theoretical studies. The...

Silicon–oxygen compounds are among the most important ones in the natural sciences, occurring as building blocks in minerals and being used in semiconductors and catalysis. Beyond the well-known silicon dioxide, there are phases with different stoichiom
