Figure 7From: Graphite/InP and graphite/GaN Schottky barriers with electrophoretically deposited Pd or Pt nanoparticles for hydrogen detectionSTM images of InP surface with Pt NPs after 1 h of EPD. Left side: the sample was annealed at 160°C for 3 min in vacuum and covered with gold layer of 9 nm in thickness by vacuum evaporation. The brightest spots represent Pt NPs while those in the background are nanograins of the gold layer. Right side: magnified STM image.Back to article page
