摘      要：The electron transport properties of a silicon atomic chain sandwiched between Au(100)leads are investigated by using the density functional theory combined with the non-equilibrium Green s function *** breaking process of Au-Si4-Au nanoscale junctions is *** conductance and the corresponding cohesion energy as a function of distance dz are *** the increase of distance,the conductance *** dz=18.098 A,there is a minimum value of cohesion *** nanoscale structure of junctions is most stable,and the equilibrium conductance is 1.71G_(0)(G_(0)=2e^(2)/h)at this *** I–V curves of junctions at equilibrium position show linear characteristics.
