Abstract

Hydrogen sensing characteristics of graphite based Schottky diodes fabricated by printing colloidal graphite on bare n-type Si substrates and those partly covered with Pt nanoparticles (NPs) was investigated. Decoration of Si substrates with Pt NPs was performed by electrophoretic deposition. We demonstrate that the post-deposition thermal treatment can extensively influence the morphology of the deposited Pt NPs as well as the sensing properties of graphite-Pt NPs/Si Schottky diodes.
