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 ...

Small Methods, EarlyView.Single‐walled carbon nanotubes (SWNTs) are promising for a wide range of applications. In particular, their exceptional electrical conductivity positions them as potential alternatives to traditional metal conductors. This review identifies the key mechanisms governing their conductivity within composites and proposes practical pathways for translating
