Polymers for micro-nano-electronics

Resp.: Prof. Saïd Sadki

Prerequisites: Master 1 level in chemistry and physics

Brief description :

This course will provide background on critical issues on the main pi-conjugated polymers/carbon structures (polymers, semiconductors and organic conductors, carbon nanotubes and graphene ) used as the active materials for electronics and energy applications. The different methods of chemical, electrochemical synthesis and recent synthetic methodologies will be reviewed. We will discuss the underlying scientific principles that guide the study of structure-property relationships and the supramolecularity effects on the modulation of electronic properties. Applications of conjugated polymers in their undoped (organic solar cell, LEDs, transistors…) doped state (antistatic layers, corrosion, actuators, electrochromic, sensors ...) will be described. In a comparative approach, similar applications of carbon nanotubes and graphene will be presented.
