The present invention generally relates to the fabrication of molecular electronics devices from molecular wires and Single Wall Nanotubes (SWNT). In one embodiment, the cutting of a SWNT is achieved by opening a window of small width by lithography patterning of a protective layer on top of the SWNT, followed by applying an oxygen plasma to the exposed SWNT portion. In another embodiment, the gap of a cut SWNT is reconnected by one or more difunctional molecules having appropriate lengths reacting to the functional groups on the cut SWNT ends to form covalent bonds. In another embodiment, the gap of a cut SWNT gap is filled with a self-assembled monolayer from derivatives of novel contorted hexabenzocoranenes. In yet another embodiment, a device based on molecular wire reconnected a cut SWNT is used as a sensor to detect a biological binding event.
本发明通常涉及使用分子线和单壁纳米管(SWNT)制造分子电子器件。在一种实施例中,通过在SWNT顶部的保护层上进行光刻图案,打开一个小宽度的窗口,然后施加氧等离子体到暴露的SWNT部分来实现对SWNT的切割。在另一种实施例中,通过使用适当长度的一种或多种二官能团分子与切割的SWNT端部的官能团反应形成共价键来重新连接切割的SWNT的间隙。在另一种实施例中,使用新颖的扭曲六苯并[2,1,9-def:6,5,10-d'e'f']二碳芘衍生物的自组装单分子层填充切割的SWNT间隙。在另一种实施例中,基于重新连接的分子线的装置用作传感器,以检测生物结合事件。
