摘要：
Using non-equilibrium Green's function method, we have theoretically investigated electron transmission through [0001]-, [1120]-, and [1100] -oriented single-atom contacts (SACs) of Ti and found that all these SACs show transmission 2.3-2.4 at the Fermi level. The transmission sensitively varies with small perturbations of contact geometry but maintains its likeliest value at ti similar to 2. Our results are compared with the experimental conductance histogram of Ti observed in our previous work (e -J. Surf. Sci. Nanotech. 12, 1 (2014)).
