- They found that the conductance does not vary linearly with the number of atoms in the contact. Since their calculation takes into account the atomic structure of the contact (by means of a tight binding approach), is not clear whether this result reflects a general property of a quantum point contact or depends on the particular crystal structure and material. Our calculation provides a simple explanation of this nonlinear behavior in terms of quantum finite size effects.
