摘要: Two types of floating-gate based organic thin-film transistor nonvolatile memories (FG-OTFT-NVMs) were demonstrated, with poly(methyl methacrylate co glycidyl methacrylate) (P(MMA-GMA)) and tetratetracontane (TTC) as the tunneling layer, respectively. Their device performances measured compared. In memory a P(MMA-GMA) typical unipolar hole transport was obtained relatively small mobility 0.16 cm2/V s. The unidirectional shift turn-on voltage (Von) due to only holes trapped/detrapped in/from floating gate resulted in window 12.5 V at programming/erasing voltages (VP/VE) ±100 V nonzero reading voltage. Benefited from well-ordered molecule orientation trap-free surface TTC considerably high 1.7 cm2/V s visible feature electrons accumulated channel trapped achieved layer. High on current...
