Band Bending in Polymer Blends of PVDF-TrFE/P3HT by Poling the Ferroelectric Component

Ferroelectric polarization is an attractive physical property for non-volatile switching, because it can be used as two binary levels for digital electronics. Here we present an integrated electronic solution by blending a semiconducting polymer P3HT and a ferroelectric co-polymer PVDF. The combination of the two polymers resulted in a ferroelectric film that by poling the ferroelectric part electronic band bending is observe on the electronic structure of the semiconducting P3HT.
