Abstract
From electronic structure calculations, we find that carriers injected into dangling-bond atomic wires on the Si(001) surface will self-trap to form l ocalized polaron states. The self-trapping distortion takes the form of a l ocal suppression of the buckling of the dimers in the wire, and is qualitat ively different for the electron and hole polarons. This result points to t he importance of polaronic effects in understanding electronic motion in su ch nanostructures.
