A COjjFe j film was electrodeposited from a bath containing trimethylaminebo-rane, TMAB to suppress the oxidation of Fe in the plating bath. It is suggested that the addition of TMAB completely suppressed the formation of Fe " in the bath before and after the electrodeposition. As shown in Table 6.1, the COj Fe j thin film deposited from the TMAB bath exhibited a B value of 23 kG, which was higher than that of the film deposited from the conventional bath. It is suggested that Fe(OH)3 inclusion was suppressed with the decrease in Fe " concentration. 

Usually the functional moiety is covalently linked to the conjugated backbone, but it can be sometimes added to ECP as a dopant when it is under an ionic form e.g., sulfonated P-cyclodextrins have been successfiilly incorporated in one step as anionic dopants in PPy by electropolymerization [230]. In some cases, electrochemistry can be combined to chemical reactions to derive functional ECPs functional PANI materials can be obtained from the reduction of the emeraldine form by alkylthiols [255] and the functionality degree on the PANI backbone can be monitored by successive oxidation-reduction cycles various functionalized PANIs can also be synthesized through electrophilic substitution or nucleophilic addition reactions [256]. For example. Figure 18.10 shows the similar electrochemical behaviors of sulfonated PANI made from reduction of emeraldine by sulfite salt followed by reoxidation, compared to thin films deposited from solution of highly sulfonated PANIs.

The thermal expansion coefficient of silicon is approximately seven times larger than that of Si02, as given in Table 2. When Si02 is deposited, typically at temperatures of several hundred degrees C, an in-plane compressive stress develops in the oxide layer as the Si wafer is cooled by AT to room temperature. For a uniform 2-dimensional thin film deposited on a substrate, the in-plane stress obtained from Equation 2 is ... 

Pauporte and Lincot [157, 158] have developed the preparation of zinc oxide thin films by cathodic deposition at 70° C from chloride aqueous solutions with dissolved zinc(II) chloride and hydrogen peroxide. 

This book is devoted to the properties, preparation and applications of zinc oxide (ZnO) as an transparent electrode material. It focuses on ZnO for thin film solar cell applications and hopefully inspires also readers from related fields. The book is structured into three parts to serve both as an overview as well as a data collection for students, engineers and scientists. The first part, Chaps. 1-4, provide an overview of the application and fundamental material properties of ZnO films and their surface and interfaces properties. Chaps. 5-7 review thin film deposition techniques applied for ZnO preparation on lab scale but also for large area production. Finally, Chaps. 8 and 9 are devoted to applications of ZnO in silicon- and chalcopyrite-based thin film solar cells, respectively. One should note that the application of CVD grown ZnO in silicon thin film cells is discussed earlier in Chap. 6. 

Figure 4.S7. SEM images of an electroluminescent phosphor particle, ZnS (used in backhght displays for cell phones, watches, etc.), before (a) and after (b) the deposition of an aluminum oxide thin film. This film is a transparent coating that prevents the phosphor particle from undergoing humidity-accelerated decay. A technique known asfluidized-bed CVD was used, where a carrier gas both delivered the precursors to a vertically aligned CVD chamber, and dispersed the powdery sample in order to expose all surface regions to the precursor vapors.

Liquid phase deposition (LPD) process is the formation of oxide thin films from an aqueous solution of a metal-fluoro complex which is slowly hydrolyzed by adding fluoride scavengers such as boric acid or aluminum metal [47], namely...
