Studying the operation characteristics and structure of vertical channel copper-phthalocyanine organic semiconductor transistor

The creation of Au/CuPe/Al/CuPc/strueture is a perpendicular type electricity found in the channel of organic static induction transistor. In the following we analyze transistor operation characteristics and machine structural relation. The results express that the transistor drives the voltage low and has no-saturation currentvoltage characteristics. Its operation characteristics are dependant on gate bias voltage and the construction of the aluminum eleetrode. The vertical ehannel of organic static induction transistor （OSIT） , with structure of Au/CuPc/Al/CuPc/ Cu, has been determined. According to the test results, the relation of its operation characteristics aud device structure was analyzed. The results show that this transistor has a low driving voltage and unsaturation Ⅰ-Ⅴ characteristies. Its operation characteristics are dependant on gate bias voltage and the structure of the aluminum electrode.     

不同炭化温度制备的C/0.5Al2O3-0.5P2O5-100SiO2凝胶玻璃的光学性质

通过醇盐不完全水解制备了含有有机基团(O-C₂H₅)的0.5Al₂O₃-0.5P₂O₅-100SiO₂凝胶,在氮气中加热到300～700℃使其中的有机基团炭化,得到镶嵌在凝胶玻璃中不同尺寸的碳纳米颗粒.利用高分辨电镜、X射线衍射和喇曼光谱研究了碳纳米颗粒的结构,发现凝胶玻璃中的碳颗粒为非晶碳纳米颗粒.测试了它们的吸收光谱,发现了由于量子限域效应引起的吸收边的移动.在532um Nd:YAG激光的激发下镶嵌有碳纳米颗粒的凝胶玻璃有一强的室温发光,发光峰在586um左右.发光峰几乎不随碳纳米颗粒尺寸的变化而变化.这种发光产生于碳纳米颗粒的表面或碳颗粒和凝胶网络的界面.
