摘　　要：A functionalized single-walled carbon nanotube (SWCNT) of a finite length with a ring-like hydrogenation around its surface is designed toward fabrication of a molecular field-effect transistor (FET) device. The molecular wire thus designed is equipped with a quantum dot inside, which is confirmed by theoretical analysis for electronic transport. In particular, the current-voltage (I-V) characteristics under influence of the gate voltage are discussed in detail.A functionalized single-walled carbon nanotube （SWCNT） of a finite length with a ring-like hydrogenation around its surface is designed toward fabrication of a molecular field-effect transistor （FET） device.
