Abstract

We have utilized the the weak localization effect in a narrow channel to measure the phase coherence time (τφ) at temperatures between 0.42 K and 4.25 K for electrons in a two-dimensional electron gas formed in a GaAs/AlxGa1-xAs heterostructure. The measured values agree well with electron-electron scattering theory in a one-dimensional channel including both single particle and collective contributions.
