The electrical properties 2D of packed metallic pentagons have been studied. The characterization of such metallic pentagon heaps (like i−V measurements) has been achieved and has allowed to point out two distinct conduction regimes. They are separated by a transition line along which the system exhibits a memory effect behavior due to the irreversible improvement of electrical contacts between pentagons (hot spots). A limit current density has been found.
