The effect of water vapor on the electrical properties and sensitivity of thin-film gas sensors based on tin dioxide
The results of theoretical and experimental studies into the effect of water vapor on the electrical conductance of a gas sensor and the sensor response to hydrogen action are discussed. A relation describing the dependence of electrical conductance $ G_{0} $ on absolute humidity in the pure air is...

| 520 | |a The results of theoretical and experimental studies into the effect of water vapor on the electrical conductance of a gas sensor and the sensor response to hydrogen action are discussed. A relation describing the dependence of electrical conductance $ G_{0} $ on absolute humidity in the pure air is derived using a hypothesis of the presence of space-charge regions depleted of electrons between the SnO2 grains in a polycrystalline tin dioxide film. Due to dissociative chemisorption of water molecules, the energy-band bending at the SnO2 grain interfaces decreases and the oxygen-vacancy concentration in the grains increases, resuling in an increase in $ G_{0} $. An equation for the sensor response to hydrogen action is derived (the $ G_{1} $/$ G_{0} $, ratio, where $ G_{1} $ is the sensor conductance in a gas mixture containing molecular hydrogen). The expression describes the dependence of $ G_{1} $/$ G_{0} $ on the hydrogen concentration ${\rm n}_{{\rm H}_2 }$ in the interval 50–6·$ 10^{3} $ ppm, band bending at the SnO2 grain interface, and sensor temperature. The dependences of the sensor conductance, highest possible conductance, and energy-band bending on temperature and absolute humidity resulting from processing of the experimental data are in good agreement with the theoretical predictions. | ||

A relation describing the dependence of electrical conductance $ G_{0} $ on absolute humidity in the pure air is derived using a hypothesis of the presence of space-charge regions depleted of electrons between the SnO2 grains in a polycrystalline tin dioxide film. Due to dissociative chemisorption of water molecules, the energy-band bending at the SnO2 grain interfaces decreases and the oxygen-vacancy concentration in the grains increases, resuling in an increase in $ G_{0} $. An equation for the sensor response to hydrogen action is derived (the $ G_{1} $/$ G_{0} $, ratio, where $ G_{1} $ is the sensor conductance in a gas mixture containing molecular hydrogen). The expression describes the dependence of $ G_{1} $/$ G_{0} $ on the hydrogen concentration ${\rm n}_{{\rm H}_2 }$ in the interval 50–6·$ 10^{3} $ ppm, band bending at the SnO2 grain interface, and sensor temperature. The dependences of the sensor conductance, highest possible conductance, and energy-band bending on temperature and absolute humidity resulting from processing of the experimental data are in good agreement with the theoretical predictions.

A relation describing the dependence of electrical conductance $ G_{0} $ on absolute humidity in the pure air is derived using a hypothesis of the presence of space-charge regions depleted of electrons between the SnO2 grains in a polycrystalline tin dioxide film. Due to dissociative chemisorption of water molecules, the energy-band bending at the SnO2 grain interfaces decreases and the oxygen-vacancy concentration in the grains increases, resuling in an increase in $ G_{0} $. An equation for the sensor response to hydrogen action is derived (the $ G_{1} $/$ G_{0} $, ratio, where $ G_{1} $ is the sensor conductance in a gas mixture containing molecular hydrogen). The expression describes the dependence of $ G_{1} $/$ G_{0} $ on the hydrogen concentration ${\rm n}_{{\rm H}_2 }$ in the interval 50–6·$ 10^{3} $ ppm, band bending at the SnO2 grain interface, and sensor temperature. The dependences of the sensor conductance, highest possible conductance, and energy-band bending on temperature and absolute humidity resulting from processing of the experimental data are in good agreement with the theoretical predictions.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Oxygen Vacancy</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hydrogen Concentration</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sensor Response</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sensor Characteristic</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Space Charge Region</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Anisimov, O.

The effect of water vapor on the electrical properties and sensitivity of thin-film gas sensors based on tin dioxide |
| abstract |
The results of theoretical and experimental studies into the effect of water vapor on the electrical conductance of a gas sensor and the sensor response to hydrogen action are discussed. A relation describing the dependence of electrical conductance $ G_{0} $ on absolute humidity in the pure air is derived using a hypothesis of the presence of space-charge regions depleted of electrons between the SnO2 grains in a polycrystalline tin dioxide film. Due to dissociative chemisorption of water molecules, the energy-band bending at the SnO2 grain interfaces decreases and the oxygen-vacancy concentration in the grains increases, resuling in an increase in $ G_{0} $. An equation for the sensor response to hydrogen action is derived (the $ G_{1} $/$ G_{0} $, ratio, where $ G_{1} $ is the sensor conductance in a gas mixture containing molecular hydrogen). The expression describes the dependence of $ G_{1} $/$ G_{0} $ on the hydrogen concentration ${\rm n}_{{\rm H}_2 }$ in the interval 50–6·$ 10^{3} $ ppm, band bending at the SnO2 grain interface, and sensor temperature. The dependences of the sensor conductance, highest possible conductance, and energy-band bending on temperature and absolute humidity resulting from processing of the experimental data are in good agreement with the theoretical predictions. |
