Figure 6From: Highly sensitive hydrogen sensor based on graphite-InP or graphite-GaN Schottky barrier with electrophoretically deposited Pd nanoparticles Current transient responses of the InP-Pd-C Schottky diode. Upon alternating exposure to the flow of gas blends H2/N2 and air. Transients upon exposure to four various gas blends are shown. The concentrations in parts per million are indicated with arrows. The diode was forward biased with the constant voltage of 0.1 VBack to article page
