摘要：

Large-area single crystalline CuTCNQ nanotube arrays (ca, 24 cm(2)) have been fabricated using an in situ organic vapor solid phase reaction by instantaneous heating (TCNQ = 7,7,8,8-tetracyanoquinodimethane).The size of CUTCNQ nanotubes can tuned by controlling file reaction temperature. The facile approach provides an important Finding for large-area synthesis of vertically aligned array organic nanotubes on conductive substrate. which is crucial to the direct fabricating of electronic and optoelectronic devices for it wide variety of potential applications. The CuTCNQ nanotube arrays exhibited excellent field emission (FE) properties and size-dependent FE properties were observed, The devices based on these highly ordered CUTCNQ nanotube arrays have been demonstrated and have exhibited excellent electrical switching effects. The maximal ON/OFF ratio of CuTCNQ nanotube arrays is about 1100. the morphology-dependent electricals switching properties of the CuTCNQ nanotube arrays were investigated. These results Suggest that the CUTCNQ nanotube array can be expected to find promising applications its field emitters and nanoelectronic devices.
