Graphite/InP and graphite/GaN Schottky barrier hydrogen sensors with electrophoretically deposited Pd or Pt nanoparticles

Original language description

By applying colloidal graphite, we prepared Schottky contacts on polished n-InP and on n-GaN wafers partly covered electrophoretically with nanoparticles of catalytic metals Pd or Pt. The nanoparticles were imaged by SEM, AFM and STM. Schottky barrier heights were virtually equal to energy of vacuum level alignments between InP or GaP and Pd or Pt (Schottky-Mott limits) - a good precondition for high sensitivity to hydrogen. Indeed, high sensitivity to hydrogen, with the detection limit below 1 ppm wasproved
