Dear Karunesh Tiwari,
As is known, CuO films is often used as a gas analyzer for CO2. Its sensitivity depends on the ability to react of the heat transfer and the electrical transmission of the laid materials for interconnections in the conductivity. Often, Ti N with silica base (or other nitrides) is used for bonding. Adding materials with less wrong resistance and good thermal conductivity will reduce the induced micro voltage, which will result in less sensitivity. But on the other hand, it will bring the sensor back to its original operating position faster.
The solution to the food problem is the search for new materials for the intermediate layer, which have fast restoring properties of heat transfer and good electrical conductivity.
