Ya. Kolesnichenko et al., RESISTANCE OF POINT CONTACTS AND SPECTROS COPY OF PHONONS IN LAYERED METALS, Fizika nizkih temperatur, 19(4), 1993, pp. 402-405
The authors theoretically studied the nonlinear conductivity of point
contacts between layered metals and analysed the anisotropy of point-c
ontact spectra of the electron-phonon interaction related to the quasi
-one-dimensionality of the electron dispersion law.
