What is the best technique (TEM or SEM) to characterize ISO and ITO films on an SiO2 substrate?

The two techniques give spectra and follow the surface compound. Analytical results had been visible with TEM with EDS, but SEM gave the only image surface with best accuracy.

How can you explain the additive effect on tin oxide to be more sensitive to pollutant gas detection?

Tin oxide SnO2 is used to detect pollutant gas due to its properties of being twice in configuration Sn4+ and Sn2+. But what is amazing is that it is more active when we add additives to it such...
