Abstract

Printed nanocomposites are of significant application potential in numerous technologies, such as touch-sensitive sensors and surfaces. Here, temperature dependent electrical transport measurements were undertaken on a recently developed screen-printed, multicomponent, nanocomposite ink to develop a detailed understanding of the electrical transport mechanisms. A theoretical model combining contributions from linear percolative conduction and nonlinear conduction attributed to field-assisted quantum tunneling successfully describes the temperature dependent conduction observed.
