摘要：

A spatial decay length of momentum-memory of an electron in GaAs-AlGaAs electron waveguides is evaluated from the nonlocal transfer resistance measurements. The ballistic mean free path LB is less than the transport mean free path since the magnitude of the transfer resistance is sensitive to the small angle scattering events. When the channel width is narrowed, LB is strongly reduced due to roughness scattering at the channel boundary. © 1990.
