Abstract

The effects of energy relaxation and the electron-phonon interaction in quasi-one-dimensional sytems were investigated. It was found that wider wires are typically described more accurately as narrow two-dimensional systems. The power loss per electron of a true one-dimensional system, was found to be significantly different than that of the wider wires. Strong deviation from the expected behavior were observed to occur at temperatures below 2 K, and was suggested to be indicative of surface/boundary effects on the power loss.
