Ballistic temperature point-contact spectroscopy in copper at 0.7 K
Reiffers M., Flachbart K., Janos S.
An asymmetry has been observed in the heating of the bulk metal banks of a point contact. This asymmetry results from a relaxation of ballistic electrons. Nonlinear structural features are seen on the voltage dependence of the bank temperature. These features are associated with N and U scattering of ballistic electrons.
