  • 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 ...
  • Rahman, Md H.; Thakur, Jagdish S.; Rimai, Lajos; Perooly, Soma; Naik, Ratna; Zhang, Linfeng; Auner, Gregory W.; Newaz, Golam (Elsevier, 2008-01-29)
    The electrical response of a hydrogen-sensing device is either a rectifying diode-type or a capacitor-type but could not be operated simultaneously in both the modes. However, we are able to demonstrate that a Pd/AlN/SiC ...
  • Erskine, Samuel K.; Elleithy, Khaled M.; Zhang, Linfeng (International Journal of Scientific and Engineering Research, 2015-03)
    The applications of WSN can be quiet numerous. In applications like battlefield monitoring, grid power generation, health systems, sensors are deployed on large scale. During such deployment, energy efficiency must be ...
  • 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 ...
