Which mechanism limits the maximum operating temperature of a polymer-based molecular electronic device?

💡 Explanation

When temperature increases, thermal energy increases the vibrational modes of polymer chains, which can exceed the intermolecular (Van der Waals) forces linking the molecules, causing bond rupture. Therefore, bond rupture occurs, rather than dielectric breakdown, electromigration, or quantum tunneling which are governed by separate physical processes under electric fields or high voltages.
