Stable n‑Type Conduction in WO _<i>x</i> ‑CNT Hybrid Films.

ABSTRACT: Nanostructured hybrid films composed of tungsten oxide (WO _x ) nanoclusters and vertically aligned carbon nanotubes (CNTs) were synthesized through a combination of chemical vapor deposition and supersonic cluster beam deposition. The use of a cluster source enabled the direct fabrication of oxygen-deficient, nonstoichiometric WO _x nanoclusters, which decorated the CNT sidewalls with a characteristic "beaded necklace-style" morphology. Electrical resistance measurements under ethanol exposure in ultrahigh vacuum revealed a distinct behavior consistent with n-type conduction, unlike the intrinsic p-type behavior of pristine CNTs and of WO _x films. This inversion is linked to the appearance of an interfacial charge transfer from the oxyge
