Abstract:The Pd/porous GaAs Schottky sensor reveals high potential for hydrogen detection at room temperature (Salehi et al 2006 Sensors Actuators B 113 419–27). The Pd/porous GaAs Schottky sensor fabricated in this study exhibited a considerable increase in sensitivity three times that of the non-porous sensor submitted to 500 ppm hydrogen gas at room temperature. The theoretical analysis presented here proves that the sensitivity of the porous sample should be more than that in the non-porous sample and this higher s… Show more
