For BSD the surface resistivity should be 10 R 10 Q cm. The best strategy for development of such materials is by incorporation of organic semiconducting polymers. Selected examples are listed in Table 4.12. 

Fig. 2.11. Three organic semiconducting polymers, (a) Polypyrrole, (b) plythipo-hene, and (c) poly(3,4-ethylenedioxythiophene) (PEDOT). All three have an sp conjugated backbone identical to polyacetylene. It is along the pi-bonds in this backbone that these materials exhibit carrier delocalization and electrical activity.

Many organic semiconducting polymers can be doped to form highly conductive materials with a variety of uses. These materials are often solution processed, which allows printing or other solution coating to be performed. When heavily doped, these materials can have conductivities approaching those of highly conductive metals.

Films of organic semiconducting polymers and organic dyes form liquid junctions (a kind of Schottky junction) when dipped into an electrolyte solution. This is a simple method of constructing photovoltaic cells.
