JUNCTION WITH TUNABLE CURRENT-VOLTAGE CHARACTERISTICS - N-DOPED SI POLY(VINYLCHLORIDE) POLY(DITHIENOPYRROLE) COMPOSITE/

A device was realized by interfacing the rectifying junction silicon/p oly(vinyl chloride)-poly(dithienopyrrole) composite with a second lith ium electrode through a polymer gel. The purpose was to tune the chara cteristics of the junction by changing the potential delivered to the polymer, Current-voltage plots of the junction were recorded at differ ent voltages applied between the polymer and the lithium electrode; pr eliminary results indicate a variation of the current-voltage characte ristics by changing the polymer potential; in particular, an increase of the reverse saturation current and a decrease of the series resista nce by increasing the oxidation level of the polymer were observed.
