"pre-treating magnesium oxide substrate superconducting material sits on, in vacuum at high temperatures, patterned microscopic hills/ valleys guiding how atoms in yttrium barium copper oxide cuprate superconducting layer settle (rather than just chemical manipulation)... creates electronic landscape at interface between layers enabling higher temperatures without superconductivity destruction... drastically reduces data center/ information and communications technology network power consumption"
