Reduced contact resistance and highly stable operation in polymer thin-film transistor with aqueous MoOx solution contact treatment

► New solution process by using aqueous MoOx solution was developed for electrode treatment. ► Polymer transistor showed the mobility of 0.1 cm2/V s. ► Contact resistance was reduced to approximately one-sixth by using aqueous MoOx solution. ► The threshold voltage shift under gated bias stress was less than 0.2 V after 105 s.
