摘要：

The ballistic transport properties of Cu nanowires (NWs) with diameter of
0.2-1.0 nm under electric field (V = 1 V/Å) are reported for future applications as
interconnections in microelectronics. Our density-functional calculations show that, under
V = 1 V/Å, with the wire diameter increasing, the number of conduction channels of a helical
atomic strand increases, whereas the number of a nonhelical atomic strand is constant within
the considered size range. The structure, electronic, and charge properties of these two types
of Cu NWs exhibit distinctly different behaviors.
