Abstract
We have fabricated devices based on oriented thin film of a conjugated polymer, namely a polythiophene derivative, which exhibited the presence of two conducting states and switching between the states. Conductance switching in such devices has been studied by photoluminescence (PL) measurements. Depending on the conducting state of the polymer, the PL intensity of the polymer showed switching between high and low values. Both the conducting states displayed an associated memory for data-storage applications. We have shown that the induced states of the polymer, which are retained for more than 2 h, can be read by the contact-less and nondestructive PL measurement.
