Properties of water by the IUPAC as being unsuitable for this purpose, since it is already the name of a cyclic ether also known as tetrahydropyran. The simplest systematic name of water is "hydrogen oxide". This is analogous to related compounds such as hydrogen peroxide, hydrogen sulfide, and deuterium oxide (heavy water). Using chemical nomenclature for type I ionic binary compounds, water would take the name "hydrogen monoxide" , but this is not among the names published by the International Union of Pure and Applied Chemistry (IUPAC). Another name is "dihydrogen monoxide", which is a rarely used name of water, and mostly used
Equivalent oxide thickness Equivalent oxide thickness An Equivalent oxide thickness is a distance, usually given in nanometers (nm), which indicates how thick a silicon oxide film would need to be to produce the same effect as the high-κ material being used. The term is often used when describing field effect transistors which rely on an electrically insulating pad of material between a gate and a doped semiconducting region. Device performance has typically been improved by reducing the thickness of a silicon oxide insulating pad. As the thickness approached 5–10 nm, leakage became a problem and alternate materials were necessary to increase the thickness
