Enhancement of electron–electron interactions in chemically synthesized polymer nanowires

We report here a comparison of electronic transport properties of conducting polymer nanowires synthesized by chemical and electrochemical methods inside nanopores. Electronic transport properties of these nanowires show a power-law behavior (I ∝ V1+β) at low temperature. Chemically synthesized nanowires exhibit higher values of β and these values increase further with the diameter of nanowires. Zero bias differential conductance of all the nanowires increase with increasing diameter and temperature but the obtained values of chemically synthesized nanowires were always found to be much lower. These results indicate enhancement of electron–electron interactions in chemically synthesized nanowires.
