Narrower bands with better charge transport : the counterintuitive behavior of semiconducting co-polymers

Article English OPEN
Fornari, Rocco P. ; Troisi, Alessandro (2014)

The narrower bands formed by donor–acceptor polymers are not detrimental to transport, as the reduced electronic coupling along the chain is more than compensated by a reduced activation energy for transport. These polymers are less sensitive to the conformational disorder of the chain as long as the bandwidth is larger than a threshold.
