초록

Thin-film transistors(TFTs) with silicon zinc tin oxide(SZTO) channel layer are fabricated by solution-process. The threshold voltage ($V_{th}$) shifted toward positive directly with increasing Si contents in SZTO system. Because the Si has a lower standard electrode potential (SEP) than Sn, Zn, thus degenerate the oxygen vacancy (VO). As a result, the Si act as carrier suppressor and oxygen binder in the SZTO as well as a $V_{th}$ controller.
