Even-odd and bulk orientation effect for monovalent atomic chain
نویسندگان
چکیده
We derive a simple three parameters conductance formula for wires with monovalent atoms. The functional form of the formula is the most general in the framework of ballistic transport through the chain. The parameters in the formula are related to the nature of the coupling of the wire to the leads and independent of the length of the atomic chain. These parameters can be determined from a first-principle calculation. The conductance formula were confirmed by atomistic calculations. One of the parameters, the phase shift strongly affects the oscillatory behavior of the conductance. We comment the results known in the literature in terms of our formula.

Observation of a parity oscillation in the conductance of atomic wires.
Using a scanning tunnel microscope or mechanically controllable break junctions atomic contacts for Au, Pt, and Ir are pulled to form chains of atoms. We have recorded traces of conductance during the pulling process and averaged these for a large number of contacts. An oscillatory evolution of conductance is observed during the formation of the monoatomic chain suggesting a dependence on the n...
متن کاملEven-odd behavior of conductance in monatomic sodium wires.
With the aid of the Friedel sum rule, we perform first-principles calculations of conductances through monatomic Na wires, taking into account the sharp tip geometry and discrete atomic structure of electrodes. We find that conductances (G) depend on the number (L) of atoms in the wires; G is G(0)( = 2e(2)/h) for odd L, independent of the wire geometry, while G is generally smaller than G(0) an...
متن کاملLow-energy ion--surface reactions of pyrazine with two classes of self-assembled monolayers: influence of alkyl chain orientation
Collisions of pyrazine with two classes of self-assembled monolayer (SAM) films are employed to determine whether surface confinement and the resulting alkyl chain orientation, influences low-energy ion-surface reactions. SAM films formed from n-alkanethiols (CH3(CH2)n-S-Au, n = 14-17) and 4-(4-alkoxyphenylbenzenethiols (4-(4-CH3(CH2)mOC6H4)-C6H4-S-Au, m = 14-17) chemisorbed onto Au (111) subst...
متن کاملAnomalous conductance oscillations and half-metallicity in atomic Ag-O chains.
Using spin density functional theory, we study the electronic and magnetic properties of atomically thin, suspended chains containing silver and oxygen atoms in an alternating sequence. Chains longer than 4 atoms develop a half-metallic ground state implying fully spin-polarized charge carriers. The conductances of the chains exhibit weak even-odd oscillations around an anomalously low value of...
