The potential of Pd/porous-GaAs Schottky contacts for hydrogen detection at room temperature is presented. The Pd/porous-GaAs contacts were developed using an electrochemical system in our laboratory. Using both forward-and reverse current–voltage (I–V) characteristics we have found that the Pd/porous-GaAs Schottky diode sensor exhibited very high sensitivity towards hydrogen gas. The Pd/porous-GaAs...
