We evaluated the effects of low-energy ultraviolet (UV) and visible light in organic thin-film-transistors, with an hexamethyldisilazane-treated SiO2 gate dielectric. After visible-light irradiation, the devices showed temporary variation in the threshold voltage, drain current, and transconductance. When UV irradiation is performed, the devices exhibit significant and permanent degradation, with a transconductance drop up to -18%.

Abstract
We evaluated the effects of low-energy ultraviolet (UV) and visible light in organic thin-film-transistors, with an hexamethyldisilazane-treated SiO2 gate dielectric. After visible-light irradiation, the devices showed temporary variation in the threshold voltage, drain current, and transconductance. When UV irradiation is performed, the devices exhibit significant and permanent degradation, with a transconductance drop up to -18%.File in questo prodotto:
