Proposed is the use of Hydrogen Peroxide (H2O2) as the ideal oxidant for atomic layer deposition of metal oxide films. H2O2 has similar oxidation properties to Ozone while simultaneously having slightly stronger proton transfer properties than water. Vital to the success of any vapor phase chemistry is delivery of stable compositions, temperature and pressure. This study demonstrates the viability of a new membrane technology for the precise delivery of H2O2/ H2O mixtures starting from a liquid range of 30-70%. An in-situ gas phase cleaning process to remove carbon contamination from Ge(100) surfaces using gas phase H2O2 has been characterized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
