In recent years, hafnium oxide (as well as doped and oxygendeficient hafnium oxide) has attracted additional interest as a possible candidate for resistiveswitching memories (ReRAM) and CMOScompatible ferroelectric field effect transistors and memory chips. A great example is Dresden based NaMLab and The Ferroelectric Memory Company (FMC ...

Subsequent removal of the organic layer by oxygen plasma and capping with SiO2 leads to the formation of a P δlayer embedded in a SiO2 matrix and spatially separated from the Si substrate. The amount of phosphorous bounded to the surface was determined by means of Time of Flight Secondary Ion Mass Spectrometry (ToFSIMS).

Oxygen, a very reactive gas, is the most abundant element on Earth. It is part of very many natural compounds, in minerals as in organic material and of course in water, H 2 O. Combustion usually is a reaction of a material with oxygen. Elemental oxygen in the form of O 2 is to 21% part of our air and is used by humans and animals for ...
