  • Thakur, Jagdish S.; Haripriya E., Prakasam; Zhang, Linfeng; McCullen, Erik F.; Rimai, Lajos; García-Suárez, V. M.; Naik, Ratna; Ng, K.Y. Simon; Auner, Gregory W. (American Physical Society, 2007-02-06)
    The time-dependant current response of Pd/AlN/ Si-based devices is investigated for different hydrogen concentrations. At a fixed applied voltage, the device current suddenly increases when hydrogen gas is turned on and ...
  • Zhang, Linfeng; McCullen, Erik F.; Rahman, Md H.; Thakur, Jagdish S.; Rimai, Lajos; Baird, Ron J.; Naik, Ratna; Newaz, Golam; Auner, Gregory W.; Ng, K.Y. Simon (Elsevier, 2006-02-27)
    The effect of Cr addition to the gate of a Pd/AlN/Si Hydrogen gas sensor was investigated by modifying the gate composition and structure. A device with a pure Pd gate responds to hydrogen concentrations as low as 1 ppm, ...
  • Zhang, Linfeng; McCullen, Erik F.; Prakasam, Haripriya E.; Takur, Jagdish; Naik, Ratna; Auner, Gregory W.; Ng, K.Y. Simon (Elsevier, 2007-04-10)
    The response transient from Pd and Pd-Ni alloy gated MIS hydrogen sensors with AlN as the insulating layer is investigated. Often we observe two distinct components of the transient response after switching on (or off) the ...
  • Zhang, Linfeng; McCullen, Erik F.; Rimai, Lajos; Naik, Ratna; Auner, Gregory W.; Ng, K.Y. Simon (IEEE, 2009-10)
    The pure Pd and Pd alloy gated metal-insulator-semiconductor (MIS) hydrogen sensors have been studied. The chemical state of palladium in Pd and Pd alloy gated devices is similar and Pd alloy devices show a wide dynamic ...
