Organic thin-film transistors (OTFTs) using high dielectric constant material tantalum pentoxide (Ta 2 O 5 ) and benzocyclobutenone (BCBO) derivatives as double-layer insulator were fabricated. Three metals with different work function, including Al (4.3 eV), Cr (4.5 eV) and Au (5.1 eV), were employ
