One-step electrodeposition of pyrrole on octadecyltrichlorosilane- (OTS) patterned silicon wafers results in positively patterned polypyrrole (PPy) structures, i.e., PPy deposits on the OTS-covered area. In contrast, negative patterns are obtained on an indium tin oxide surface. The Figure shows electrically isolated positive PPy microwires on a silicon wafer.
