Latest Patents

Xing-Cai Guo holds a patent for "Nitrogen doped oxides for lower bandgap." This invention addresses the challenge of nitrogen doping in magnesium oxide (MgO) to lower the bandgap of magnetic storage devices. By adding a cation, he enables magnesium to retain the nitrogen dopant without excessive oxidation or nitriding. The resulting nitrogen doped MgXO, where X represents the cation, exhibits a lower bandgap compared to similar barrier layers lacking nitrogen or a cation. This advancement improves both thermal and electrical reliability in magnetic storage applications. Notably, the nitrogen doped MgXO is non-stoichiometric, contrasting with stoichiometric oxynitrides. Potential cations for this process include aluminum, titanium, vanadium, chromium, and scandium.
