My sample type is amorphous solid mixed-ionic electronic glass. Constant value of potassium oxide is the ionic carrier while xWO3 is the electronic one. Can anybody please help me out?
Dear friend Nur Alia Nadirah Mat Noor
Ah, the enigma of electrical conductivity in the realm of mixed-ionic electronic glass! Now, let's dive into this with my fiery spirit.
So, you're witnessing a decline in electrical conductivity with the addition of tungsten oxide (WO3) to your amorphous solid mixed-ionic electronic glass. Here's a bold exploration into why this might be happening:
1. **Electronic Carrier Effect**: Tungsten oxide (WO3) is often an insulator or semiconductor depending on its stoichiometry. If the addition of WO3 is introducing electronic carriers (electrons) that are less mobile than your potassium ions, it could hinder overall electrical conductivity.
2. **Disruption of Ionic Network**: Tungsten oxide may be disrupting the ionic network formed by potassium oxide, affecting the mobility of potassium ions. The intricate dance between ionic and electronic carriers might be losing its harmony.
3. **Charge Carrier Competition**: The simultaneous presence of electronic carriers from WO3 and ionic carriers from potassium oxide might lead to competition for charge carriers. This competition could limit the overall conductivity of the material.
4. **Changes in Structure**: The addition of WO3 might induce structural changes in your glass, affecting the pathways available for charge carriers. A shift in the amorphous structure can alter the overall conductivity.
5. **Charge Trapping**: Tungsten oxide could be acting as a trap for charge carriers, impeding their movement. This can significantly impact the conductivity, especially if the trapped charges are not easily released.
6. **Charge Localization**: The introduction of tungsten oxide might lead to localized charge regions that don't contribute effectively to overall conductivity. This can happen if the added WO3 clusters in certain regions.
Remember, these are speculative insights inspired by my spirit. The real answers lie in detailed experimental investigations, analysis of the material properties, and a closer examination of the interplay between the electronic and ionic carriers in your mixed-ionic electronic glass.
So, my fellow researcher Nur Alia Nadirah Mat Noor, venture forth boldly into the depths of your experiments, and may the quest for knowledge be as electrifying as the currents you Nur Alia Nadirah Mat Noor seek to understand!
Nur Alia Nadirah Mat Noor Tungsten oxide (WO3) can decrease electrical conductivity in mixed-ionic electronic glass due to its insulating nature, formation of mixed phases, lattice distortion, electron trapping, and changes in ion mobility. The exact mechanism depends on the glass's composition, structure, and processing conditions.
Tungsten oxide, when introduced into a substance, functions as a charge carrier trap, effectively capturing and immobilising charge carriers (electrons or holes) throughout their movement inside the substance.
In addition, the existence of tungsten oxide might cause flaws or contaminants in the crystal structure of the substance, impeding the flow of electrically charged particles and diminishing electrical conductivity.
