Abstract：

The　modified　layer　of　the　device　dielectric　layer　on　the　Si/SiO2　substrate　was　prepared　using　polymethyl　methacrylate(PMMA),　which　improved　the　interface　quality　of　the　dielectric　layer　and　induced　the　growth　of　the　active　layer,　thereby　increasing　the　crystallinity　of　the　active　layer.The　organic　thin　film　transistor　(OTFT)　was　prepared　by　vacuum　evaporation　of　a　pentacene/rubrene　double　layer　active　layer,　and　the　effect　of　device　performance　on　the　thickness　of　the　rubrene　layer　was　investigated.　The　test　results　show　that　the　threshold　voltage　of　the　modified　device　is　-3.55　V,　the　current-switching　ratio　is　more　than　105,　the　mobility　reaches　0.0558　cm2/V•s,　and　the　subthreshold　swing　is　1.95　V/dec.　These　data　suggested　that　the　overall　performance　of　devices　with　the　modification　of　PMMA　layer　was　successfully　improved.　©　2020,　Journal　of　Synthetic　Crystals　Press　Research　Institute　of　Synthetic　Crystals　Co.,　Ltd.　All　right　reserved.
