Influence of ultraviolet radiation on surface electric potential of the p(vdf-trfe 70:30) films deposited on glass substrate

Abstract

Ultraviolet (UV) radiation is able to cause biological changes at the cellular and molecular level. These biological structures are nano- and micro-sized, so to study the effect of UV radiation, detector is required, commensurate with their size. Ferroelectric P(VDF-TrFE 70:30) films deposited on a glass substrate were examined as a possible sensor of UV radiation. Changes in surface electric potential of the P(VDF-TrFE 70:30) films under UV radiation were investigated by Kelvin force microscopy.
