Fig. 14.5 I–V curves of SnO 2 samples.: 1, 0D SnO 2 ; 2, 1D SnO 2
dimensions. However, the most promising is the CVD method, which results in
the obtaining of SnO 2 single crystals of high crystallinity degree; the synthesized
powders have higher values of the specific surface area and are characterized by
better adsorption properties.
