Electron Transport in a Multi-Channel One-Dimensional Conductor: Molybdenum Selenide Nanowires

Abstract

We have measured electron transport in small bundles of identical conducting Molybdenum Selenide nanowires where the number of weakly interacting one-dimensional chains ranges from 1-300. The linear conductance and current in these nanowires exhibit a power-law dependence on temperature and bias voltage respectively. The exponents governing these power laws decrease as the number of conducting channels increase. These exponents can be related to the electron-electron interaction parameter for transport in multi-channel 1-D systems with a few defects.
