Özet:

 

Hydrogen gas sensors, based on palladium membranes, have   considerable applications in areas such as industry, aerospace, and green   energy monitoring. In this paper, we propose a surface plasmon resonance   nanosensor, in which the main metal sensor is taken to be gold with a thin   nanolayer of palladium membrane. The reason we chose palladium is its   exceptional property of having high permittivity to hydrogen penetration. In   this paper, formation of palladium hydride (PdHxx_{x}, where x = H / Pd) is   achieved and simulation is provided using Materials Studio software. Based   on an intermediate assumption, a semiconductor gold composite layer is used   instead of gold, because the composite layer gives higher efficiency. In the   final structure, twelve alternating layers of gold and silicon are used   (silicon and gold with thicknesses of 0.53 and 13.6 nm, respectively). The   proposed structure is simulated under carbon monoxide exposure to analyze   its cross-sensitivity to other gases. Finally, the sensor shows higher   sensitivity and narrower linewidth under hydrogen exposure compared to   carbon monoxide exposure.
