Small, EarlyView.A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...
