摘要

We report an experimental investigation of magnetic focusing in the 1D non-equilibrium transport regime and utilize it to study the energy variation of electrons propagating through a quantum point contact. The results give insight into the behavior of electrons with different energies when current is both unidirectional and bidirectional, in particular, a splitting of the focusing peaks which demonstrates that the intrinsic resistance within the point contact is negligible and that the voltage drop is at least 3 μm away from the ends of the point contact.
