Using first-principles calculations based on density-functional theory, the effects of adsorbates (CO molecule, O and N atoms) and defects (an adhered atom and a monovacancy) on structural and electronic properties of the smallest (4, 4) AgNT have been systematically investigated. For CO adsorption on energetically preferred top site, the donation–backdonation process between the CO and Ag states leads to the formation of bonding/antibonding pairs, 5σb/5σaand 2πb∗/2πa∗, and the quantum conductance of AgNT decreases by 1G0after CO adsorption. Both O and N atoms strongly interact with AgNT after adsorption, leading to a 3G0and 2G0of drop in quantum conductance, respectively, for the AgNT. High adsorption energy of adhesion of one Ag atom and relatively low formation energy of a monovacancy suggest that these two types of defects are likely to occur in the fabrication of AgNT. The quantum conductance of the AgNT remains unchanged for adhesion of one Ag atom, but decreases by 1G0when a monovacancy is present.
