Study Nanostructured Sensor Films

As discussed above, the concentration of chemisorbed ions at the surface is related to the partial pressure of the gaseous species according to Eq. (4), and increases with an adsorption coefficient, (3. The relationship between (3 and the electronic properties of the semiconductor was originally derived by Vol kenshtein and reproduced by Rothschild and Komem [29]

Case Study Interfaces in Ionic and Mixed Conducrting Materials 

The electrical conductivity of an ionic solid, like that of a semiconducting solid, is normally controlled and enhanced by homogeneous doping, in which a donor and/or an acceptor species is substituted on specific lattice sites. Such doping occurs 

1) Exceptions exist such as Ag ion conduction in otAgl in which the Ag sublattice is intrinsically disordered.

This chapter aims to explore the major studies using AFM for conductive polymers, focusing on the application of images and force spectroscopy for nanostmctured films, nanostructures, and sensors. 

As naturally abundant and low-cost semiconductor, NiO is widely used in electrochromic windows [20], batteries [21], supercapacitors [22], and sensors [23], While all these applications benefit from an interconnected, three-dimensional NiO nanostructure that combines a high specific surface area with a good electric conductivity, the performance enhancement becomes vividly evident as an increased coloration contrast and improved switching behavior when applied in electrochromic devices. NiO nanomaterials recently employed in electrochromic studies include nanocomposites [24], inverse opals [25], macroporous [26] and mesoporous films [27-29],...
