Abstract

Point-contact (PC) spectroscopy has been shown to be a very useful experimental method for the direct study of the energy dependence of the interaction between conduction electrons and quasiparticle excitations in metals [1]. For small PC between two metals where both the inelastic le and elastic li mean free paths of the electrons are larger than PC diameter d, the electron transport through the PC is ballistic. Then the applied voltage directly defines the energy scale for the scattering processes of the accelerated electrons. In this case the second derivative d2I/dV2(eV) of the I–V characteristic is directly proportional to the electron-quasiparticle interaction function.
