This tendency reflects that the gas transport problem becomes less important as L decreases. 5. TRANSIENT PROPERTIES So far, we were concerned with the gas sensing properties at steady state. It is possible to solve the diffusion equation (1) under non steady state conditions based on the equivalent model in figure 5 (b). The boundary conditions are the same as those used previously: C=CS at JC=0 and 2L. The initial condition is: C=0 at any points inside the film at r=0. The solutions is expressed as follows.

Yamazoe, "Preparation of Stabilized Nanosized Tin Oxide Particles by Hydrothermal Treatment," Journal of American Ceramic Society, 83| 12] 2983-2987 (2000). S. Baik, G. Sakai, K. Shimanoe, N.

The results from the 3-D graphs are consistent with the ones in 6(b). As mentioned earlier lower thermal amplitude indicates better bonding, the results reveal that samples heat treated at 700°C shows better bonding than samples heat treated at 1000°C. However results obtained from TWI are not always unambiguous, because the thermal diffusion depends on the porosity within the film also. Thus quantitative adhesion test were tried to get a better idea about the system. Nano-indentation test As mentioned earlier, during nano-indentation a diamond tip indents the surface of the film to evaluate material properties such as elastic modulus and hardness.
