项目摘要
Organic Thin Film Transistor (OTFT) memories with a nanocrystal carbon (nc-C) dots arranged in channel region were fabricated using a focused ion beam (FIB) system with a precursor of low energy Ga^+ ion and carbon source. The crystallinity of nc-C dots was investigated by Raman spectroscopy and atomic force microscopy (AFM). Raman spectra indicate the evidence of crystallization of nc-C after annealed at 600℃ by the sharp peak at 1565 cm^<-1> in graphite (sp^2), while no peak of diamond (sp^3) could be seen at 1333 cm^<-1>. The AFM images showed the nc-C dots controlled with diameter of 100 nm. The above results revealed that the nc-C dots had sufficiently stick onto SiO_2 films. The hysterisis loop in the threshold voltage characteristics appeared in the device in which voltage shift is 0.32 V after charge injection into the nc-C dots.. In next stage, we will analyze the erase step and retention characteristics.
采用低能Ga^+离子和碳源为前驱体的聚焦离子束(FIB)系统制备了沟道区排列有纳米碳(nc-C)点的有机薄膜晶体管(OTFT)存储器。利用拉曼光谱和原子力显微镜(AFM)研究了纳米碳点的结晶性。拉曼光谱表明,纳米碳在600℃退火后,在石墨(sp^2)中1565 cm ↑ [2]处出现尖锐的峰<-1>,而在1333 cm ↑ [2]处没有观察到金刚石(sp^3)峰<-1>。原子力显微镜图像显示纳米碳点控制在100 nm的直径。上述结果表明,纳米碳点已充分粘附在SiO_2薄膜上。阈值电压特性中的滞后环出现在器件中,其中在电荷注入到nc-C点之后电压偏移为0.32V。在下一阶段,我们将分析擦除步骤和保持特性。
