Role of stability of the structural state in the change in microcontact spectra of zinc single crystals

This study is devoted to the problem of obtaining microcontacts with a controllable structure and geometry. Laws are established which govern the change in features of microcontact spectra (MCS) in the presence of stable and metastable small-angle twist boundaries in material subjected simultaneously to mechanical loading and a high-density electric field. It is shown that the effect of basis dislocations on the MCS can be discerned thanks to the fact that the field of internal stresses from dislocations pinned in a hexagonal network is considerably greater than the diameter of the microcontact. A quantitative study is made of the parameters characterizing the MCS with a specified structural state in the micro-contraction region. The effect of instability of the structural state resulting from alternating torsion on the MCS is also examined.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 12, pp. 65–68, December, 1989.In conclusion, we would like to thank I.
