Abstract (English)

Simultaneous two- and four-point measurements are used to characterize the polymer bulk as well as the contact resistance of polypyrrole and polythiophene films. Polythiophene films obtained were electrochemically and spectroelectrochemically characterized in aqueous and organic electrolytes. Sensor chips containing not only four electrodes for resistance measurements, but additionally two ...


Translation of the abstract (German)

SImultane 2-u. 4-Punkt Messungen wurden verwendet, um den Filmwiderstand sowie den Kontaktwiderstand von Polypyrrol- und Polythiophen-Filmen zu charakterisieren. Polythiophene Filme wurden elektrochemisch und spektroelektrochemisch in wässrigen und organischen Elektrolyten charakterisiert. Sensor-Chips, die nicht nur vier Elektroden für Widerstands-messungen, sondern zwei zusätzliche Elektroden ...
